A full winter has come and gone since last we visited Westeros. But now, "Game of Thrones" returns, promising bitter winds and worse betrayals all throughout its fifth season.

Before turning our attention to season five, however, one last look at the past. What do we need to remember from season four of "Game of Thrones" before we move onto Jon Snow, Tyrion Lannister and Daenerys Targaryen's next adventures? And just in case this doesn't do it for you, you can always check out our catch-up in peanuts (not a joke):

Joffrey died.

And it. Was. AWESOME. Not so awesome for the Lannister siblings, for a variety of reasons, with Cersei and Jaime (but mostly Cersei) mourning their son, and Tyrion standing accused of his murder.

Sansa ran.

As Tyrion's wife, she was looked at as a possible suspect in Joffrey's death. Too bad she's nowhere to be found in King's Landing, since Littlefinger whisked her away to the Vale to live under his protection, and under a new name: Alayne Stone, Littlefinger's "bastard daughter."

Littlefinger killed.

Chaos is a ladder, as well as a moon door. Shortly after marrying Lysa Arryn, Littlefinger murdered his bride and assumed control over the Vale, adding another jewel to his increasingly ornamental crown on his quest to attain "everything." With added power under his belt, and Sansa at his disposal, his next move is anyone's guess.

Tommen ascended.

Meanwhile, back in King's Landing, a new power player emerged: Tommen Baratheon. With his older brother dead, little Tommen became the new king of Westeros. Among the perks: Margaery Tyrell as a fiancé, and all the time in the world to hang out with the best cast in the Seven Kingdoms, Ser Pounce. Among the drawbacks: Mama Cersei helicopter-momming over his every single move.

The Mountain smashed.

With his trial becoming an increasingly obvious farce, Tyrion demanded trial by combat, with the Red Viper of Dorne as his champion. Despite a belly full of fire and vengeance, Oberyn Martell wasn't able to fulfill his vendetta against House Lannister. Instead, his head was squeezed in like a melon at the hands of Gregor Clegane, in what's pretty easily the goriest death in "Game of Thrones" history.

The Hound howled.

Speaking of Clegane, pour one out for Gregor's little brother, Sandor. The Hound spent most of season four hanging out on the road with Arya Stark, but their buddy comedy came to a tragic end when they encountered Brienne of Tarth. Rather than handing Arya over to Brienne, the Hound engaged Jaime Lannister's BFF in a big ol' battle that ended with him earless, thrown off a cliff, and near the end of his life. However…

Arya ran.

The little wolf refused to put an end to the Hound's misery, leaving him to die slowly from the wounds he sustained while fighting Brienne. Instead, she went off on her own, and found a ship set to sail for Braavos. She bought passage aboard the ship by presenting her old face-changing friend Jaqen H'Ghar's coin and uttering the words, "Valar morghulis." With that, she finally freed herself of Westeros, on a collision course with the great city that was once home to her late water-dancing instructor, Syrio Forel.

Anyway, back to Tyrion…

The Imp's fate seemed all but sealed after Oberyn's brutal death, but wait! Not so fast! Big brother Jaime and scheming eunuch Varys conspired together to free Tyrion from prison on the night before his execution. Yay for Tyrion!

Tyrion snapped.

But as a wise man once sang, freedom isn't free. Upon his escape, Tyrion's first order of business was to execute his ex-lover Shae, who had betrayed him publicly during the trial, and privately in the bedroom by sleeping with his father. "I'm sorry," he muttered pathetically, seconds after choking the life out of her.

Tywin died.

As if murdering Shae wasn't enough, Tyrion proceeded to slam two crossbow bolts into Tywin, while daddy dearest was having a private moment in the privy. The Lannister patriarch's demise spells out all kinds of trouble for not just Tyrion, but everyone in King's Landing, and potentially everyone outside of it.

Tyrion and Varys hit the road.

If Tyrion's going to get into trouble for killing his father, it won't be in King's Landing, at least not anytime soon. Like Arya, Tyrion became the latest character to ditch Westeros for parts unknown, boarding a boat with Varys and leaving the Seven Kingdoms behind for good — or, at least, for now.

Jon battled.

In the North, the bastard son of Ned Stark was in full-on Night's Watch mode all season long, doing his duty to defend the Wall against Mance Rayder's army of giants and mastodons. With the help of Stannis Baratheon, the Watch overcame the wildlings, but at the expense of several lives — including Ygritte, Jon's former flame.

Bran warged.

Even further North, Bran and his friends finally traveled beyond the Wall and wound up meeting the Three-Eyed Raven. Turns out, he's just an old dude who lives underneath a tree, with a bunch of weird little tree-children serving at his whim. Also, Jojen died. Also, we're not going to see Bran this season, so maybe you don't need to remember this storyline? Just in case, it happened.

Daenerys conquered.

Far east of Westeros, Daenerys Targaryen, the First of Her Name, Queen of All Cool Things and Other Sundry Titles, sacked Meereen and took control over the great Essos city. Guess she's not making it to Westeros anytime soon?

Daenerys lost.

While she squashed slavery in Meereen, Dany couldn't avoid putting her own children in chains. After Drogon killed a child and flew off toward who-knows-where, Dany was left with no choice but to lock her two remaining dragons away in an underground dungeon. Will we see her fire-breathing beasts this season? Well, it wouldn't be "Game of Thrones" without some dragons, so you be the judge.

EVERYTHING happened.

That's the highlight reel, but so much more happened, from White Walkers converting babies to their cause, to Theon Greyjoy becoming more like an animal and less like a man with each passing breath, to Stannis striking an allegiance with the Iron Bank of Braavos, to Daenerys exiling her trusted advisor Jorah Mormont after learning about his sordid past… the list goes on and on and on. In other words, you're armed with the greatest hits of season four, but if you REALLY want to remember all of the nitty-gritty details… well, a "Game of Thrones" rewatch isn't the worst thing in the world, is it?
