We here at MTV News know just how stressful shipping can be. One minute your OTP is happily in love and the next, they're being torn apart by the cruel realities of fate -- or, you know, vampires. But what about those ships that always keep us hanging?
You know the ones. You think they're just friends until one longing glance changes everything. Suddenly, you start questioning every chaste kiss, "platonic" hug and bit of playful banter until your brain is about to explode. What are the chances that these frustrating couples will ever get together? Well, we're happy you asked.
In honor of Valentine's Day, MTV News tracked down your favorite TV actors and showrunners to talk about the ships that are currently sailing through ambiguity. Is there a chance any of them will weather the storm? Find out below.
Olicity, "Arrow": 50%The CW
"I’m going to be a dick," warned "Arrow" boss Marc Guggenheim. "I’m going to be a dick and say 50-50. In large part because I want to see what the internet does with that comment. I can see them losing their minds, but that’s part of the fun. That’s one of the perks of my job, is getting to see what the internet does."
Oliver and Felicity have seen quite a few ups and downs this season, especially with Oliver's almost-death. Despite managing to make it home to Starling City in one piece, Oliver couldn't quite manage to keep Felicity. After he broke the news to her that he needed to train with Malcolm Merlyn in order to defeat Ra's al Ghul, she broke Oliver's heart -- and ours -- when she walked away.
"I think Oliver did the heroic thing, and made a selfless choice to put what he’s doing right now ahead of any potential relationship with Felicity," Guggenheim said. "I don’t think he expected Felicity to react the way that she did. So I don’t know how premeditated the decision was on Oliver’s part. One of the things I like about that scene between the two of them -- I think it’s the audience response too -- Oliver and Felicity both have a very strong point of view, and a very defensible point a view, in that final scene of episode 12. Whenever you can maneuver your characters into a situation where they both have a good argument to make, you’re on the right track."
"Felicity is really coming into her own this year and standing up for herself," he added. "We’ve seen Felicity stand up to Oliver and stand up to Malcolm Merlyn, and it really works. Emily brings such an inner strength to it. We’ve got a scene coming up in a future episode where you won’t believe who she stands up to, and how she does it. It will really surprise people."
Steroline, "The Vampire Diaries": 80-90%The CW
After seasons of sexual tension and "will they, won't they" moments, it looks like Stefan and Caroline might actually become an official item on "The Vampire Diaries" -- and Steroline captain Paul Wesley (Stefan) couldn't be happier.
"I would put money on it," Wesley said. "As a Wall Street guy in my movie ["Amira & Sam"], I would definitely say that’s a safe bet. 80, 90 percent. It’s in that range, for sure."
Emison, "Pretty Little Liars": 0%*ABC Family
*"It's really hard to give you a percentage because that would have an impact on how you access Alison's status, since she's in jail right now," "Pretty Little Liars" executive producer Joseph Dougherty said. "So that number is based on whether she gets out of jail. I'd have to say that any chance for them to get together and work on their relationship is entirely dependent on what's going to happen to Ali and whether she walks away from this rather substantial charge. I would say zero percent would be a safe number, with an asterisk. The zero will freak everybody out, I'm sure."
But Emison stans shouldn't be too discouraged. According to Dougherty, there's still plenty of story to tell between Ali and Emily. After all, you never forget your first love -- even if you do think she murdered multiple people and terrorized you and your friends for years.
"If you look at the four girls, Em is the one who's never completely 100 percent -- we're back to percentages!" he said. "It's arguably the most unresolved relationship, among the four Liars. The thing I keep coming back to is that it's also made complicated by the fact that Emily is really not the same girl that Alison left behind. I people identify with Emily because everyone remembers the first crush and spends a lot of time thinking, 'Was that really love, or was I just being crazy?' Emily is just trying to figure all of these feelings out."
As for Ali, she's still an enigma. While we want to believe that her feelings for Emily are real, she's a master manipulator, and that's not something we take lightly.
"Meanwhile, Alison is someone who's been incredible protective of her emotions," he added. "I don't think Alison has ever let anybody all the way in, emotionally. So maybe people are fascinated by the couple because they see these big barriers more clearly."
Caryl, "The Walking Dead": 35%AMC
While it's unlikely anyone on "The Walking Dead" will ever get a happy ending -- sorry, shippers -- that doesn't mean we're not holding out hope for fan-favorites Carol and Daryl. But is their broken friendship beyond repair?
"I think the chances are better now that Beth is, sadly, out of the picture," "Walking Dead" boss Greg Nictotero said. "But the truth of the matter is that Carol is definitely in a different place now than she was when they were friends. You don't really get the sense that they're as close as they used to be. That kind of banter that Carol had with Daryl had in previous seasons, seems to be diminished a bit because of everything that she's gone through. I just think it's all really changed Carol. She's much more hardened than she was in previous seasons."
Brallie, "The Fosters": 45-50%ABC Family
Oh, Brallie. Callie and Brandon's relationship on "The Fosters" isn't your typical angsty teen romance. For Brallie, the stakes are much higher. Why? Well, because they're pretty much adopted siblings. (Okay, so Callie hasn't been technically adopted by the Fosters yet, but she still lives under their roof.)
"The thing about Brallie that is different from a lot of ships is that the fans are completely divided, like straight down the middle," showrunner Peter Paige told us. "And I think the percentage chance that Brallie will happen this season is right around the 50-50 mark, maybe 45-55."
"We have this incredible challenge," he added. "Callie needs a family; it happens to be Brandon's family. And she can't have both, so as things more forward with Callie's adoption, the likelihood of Brallie happening seems to disappear, but the connection between them is undeniable -- and they are teenagers, and they are driven."
WestAllen, "The Flash": 85% -- maybeThe CW
Iris West and Barry Allen are pretty much cannon in the DC Comics universe, but their television counterparts are taking things slow on "The Flash." Barry made his feelings clear to his BFF Iris, and at the time, she didn't reciprocate them because of her relationship with Eddie. But now that Barry has a new girlfriend, will Iris start to question her own feelings for her childhood best friend?
"I don't know about this season, but in the future, it's probably very likely," Candice Patton told us. "I don't see why it wouldn't be. It's such an iconic coupling in the 'Flash' series. But I can't say anything is 100 percent on this show, so maybe 85 percent. They could literally do anything they want."
FitzSimmons, "Agents of S.H.I.E.L.D.": Exactly 50%ABC
Brainy best friends Jemma Simmons and Leo Fitz were torn apart at the end of season 1 when Fitz confessed his feelings for Simmons and then went and got his memories swiss-cheesed -- convenient, right?
"I think when we initially presented them to the world, there was something about their chemistry that was already apparent," co-showrunner Maurissa Tancharoen told us. "They're both scientifically like-minded individuals and that's how their initial bond took place. And because of their banter, we were implying that there was something there."
"Not only the characters, but the actors instantly had chemistry when we first paired them together," and co-showrunner Jed Whedon added. "It was blatantly obvious during their auditions. And they're like brother and sister."
As it turns out, their separation may be the thing that ultimately brings FitzSimmons back together again, as both characters got to take time for themselves this season.
"Their relationship this year, coming back from not only Fitz's confession but also his injury, their dynamic has changed," said Tancharoen. "So when we see moments of them actually coming together, it's gratifying. But they both have to grow up and go their own separate ways, and that happens in a lot of relationships. In the meantime, it's nice to see them thrive as individuals."
Grenna, "Chasing Life": 82.7390210%ABC Family
Perhaps no other ship on this list has captivated social media quite like "Chasing Life"'s star-crossed lovers Grenna. Greer and Brenna are the epitome of opposites attract, and their "Juliet and Juliet" relationship is the stuff lovelorn fanfics are made of.
"I would say it's 82.7390210 percent likely," executive producer Patrick Sean Smith said. "Next week's episode is a huge game-changer for Greer and Brenna. Greer has been holding onto a secret that's been keeping her from Brenna all this time, and next week, we find out what that is. And then Brenna reveals something to Greer and to the audience that she hasn't shared with anybody on the show yet. And that is huge."
"Their fundamental difference is interesting," he added. "With Greer, to see a girl in a private school be out and be successful and happy is encouraging and exciting, and I think putting that against all of the heartache that Brenna has endured -- with the loss of her father and her sister's diagnosis -- is compelling. And where we've taken them so far in their relationship, with Greer needing to defy her parents and be a little less of a good girl and Brenna needs to be a little less of a bad girl, they just balance each other out really nicely."
