Life with Derek ended seven years ago, but fans haven't stopped shipping the two lead characters, Casey MacDonald and Derek Venturi — even though they're stepsiblings.

"People can't get enough of Dasey," Ashley Leggat said during a phone interview with her costar Michael Seater and MTV News. The semi-controversial, non-canon ship is still currently discussed on social media and the actors became aware of it early on. Seater explained how they thought it was hilarious and didn't see anything wrong with it.

And because it was always at the back of their minds, and the fans were so into Casey and Derek being a couple, Seater noted how actors always want to find subtext in their lines and give fans what they desire. Leggat pointed out how Dasey was just like the experience of simultaneously hating and loving someone, since the stepsiblings rarely got along, but did prove to be there for one another when it really counted.

When asked about Dasey-themed GIFs and photosets they've seen on Tumblr, Seater shared the one he sees most often comes from the series finale.

However, neither actor could share any Dasey fan fiction they've read over the years simply because it's way too inappropriate. Leggat described it as "super X-rated," while Seater explained he "was shocked at the things that people were coming up with."

Dasey fanfic writers don't mess around or hold anything back, and fans still repeatedly ask Seater and Leggat to make out — despite the fact Leggat has been married to professional hockey player Jeremy Williams since 2011. Of course, a myriad of the series' viewers think she's actually married to Seater, who played a hockey player on Life with Derek.

But they totally understand the shipping desire. "I remember watching shows when I was growing up and just wanting these two people on the show to be together because they seem so perfect together," Leggat said. "You don’t want to ruin that fantasy [of Seater and Leggat ending up together] for people, because that’s what they loved about Life with Derek."

While the spin-off series, Life with Derek, Again, never came to fruition, there was a script. "I can tell you the pilot started with Casey and Derek in bed together ... [but] I’m not gonna tell you the context of it," Seater teased.

In fact, Seater revealed he thinks the duo should've ended up together on the show, and perhaps they did — in some kind of Twilight Zone parallel universe, that is. Leggat explained how it just made sense for Casey and Derek to be together and is "a natural progression for them."

Both actors proudly ship Dasey and want fans to continue shipping the stepsiblings. "Never give up. Keep on shipping," Leggat said, with Seater adding, "You never know."
