EW.com talked with Michael Cudlitz, who plays Abraham on TWD, and they asked him why Abraham seems to be interested in Sasha even though he has a girlfriend in Rosita. We know in the comics, Abraham cheats on Rosita with a character named Holly (who was in the TV show for a brief time before getting killed by the Wolves) and that breaks him and Rosita up, but what will the TV show do? Besides Maggie and Glenn, the show hasn’t had many intimate relationships with characters the past few seasons, so this could be good for the viewers that like that stuff.

Here’s what Cudlitz had to say:

… he sees a lot of himself in Sasha, things that he has respected his whole life – the strength that she has on her own. I think in a lot of ways he feels like he’s protected Rosita, and he’s brought her to this point through training her, and here is someone that he’s looking at, and he’s seeing an equal who will call him on his bull. So he’s attracted to that. So, you know, we’ll see what that really evolves into.

I don’t know if at this point he really knows what it is, but he knows he likes it. He knows he’s attracted to it, and he knows at this point, there’s nothing denying it. I would equate it to somebody when they know they’re going to die. You have to do changes in your life, and I think he’s in this sort of world. He’s sort of said, “Okay, this is where we are, and I’m not going to live any lies.” I’m going to move forward, and I’m going to do what I have to do.”

…

I think when characters have hope and they know that there’s a future, they reassess, and I think he’s going through a major reassessment right now knowing that, as he says in the episode, we have walls. You know, we have a future. And beer.
