To recap the Lannister soap opera on Game of Thrones: Tyrion, Jaime, and Cersei are all Lannister siblings. Jaime and Cersei are lovers (gross!). Tyrion and Cersei hate each other. Tyrion and Jaime have always been pretty chill with one another. Cersei puts Tyrion in prison after accusing him of the death of her son (whose father is Jaime). Jaime helps Tyrion escape—but before Tyrion leaves, he kills their father Tywin. It's a pretty fucked up family.
As we've learned, all of these characters will begin to converge in Season Seven, which means the Lannister family will be back together again for the first time since season four. As you could imagine, it's not going to go well! As Peter Dinklage told Entertainment Weekly:
He's returning home, and returning home a new person. He has Dany and the dragons on his side but he is a very different person than when he left this place. And he's returning to a brother he loves and a sister he ... dot dot dot ... He's bracing himself.
Yeah, and Westeros will be a much different place than how he left it. All his nieces and nephews are dead, his sister killed all the important people in King's Landing, and she's now sitting on the Iron Throne as the Mad Queen. Oh, and there's also an army of horrible White Walkers invading from the North. There's also Jon Snow, who is Daenerys's nephew (and possibly Tyrion's relative, too), who is now King of the North.
While all of this is depressing as hell, the good news is that Tyrion is no longer an alcoholic who has nothing better to do than drink and sleep with women.
"He was just going to drink himself to death after the end of Season Four, then Varys gave him a purpose in life and then in Daenerys he saw somebody he could get behind," Dinklage explains. "That's what somebody like Tyrion needs—he needs a gig to get behind. Give him a drink and he doesn't do so well."
At least he's got that going for him, which is nice.
