Juan Diego Botto tells TooFab: "We have this fantasy of who we want to be, but who are we really?"
Letty has gone back to living the high life on TNT's "Good Behavior" and it's driving a huge wedge between her and hitman boyfriend Javier.
In an exclusive sneak peek at Sunday's new episode, a tweaked out Letty (Michelle Dockery) gets a phone call from Javier (Juan Diego Botto), who doesn't quite get the reaction he was hoping for when he tells her he's purchased a 3-bedroom house for them to live in as a family.
He's determined to make it work for them and Letty's son Jacob, but she's in a downward spiral after deciding she's not fit to be the parent she needs to be.
The clip shows a Letty who, without her son and without Javier, has really gone off the deep end. Will they figure it out before it's too late?
"One of the characters from this episode says, 'It's not fun if it's easy.' And it really wouldn't be fun for the audience either," Botto explained to TooFab. "These two characters keep trying to find themselves. Sooner or later, they'll be confronted with that question, 'Who are we really?' We have this fantasy of who we want to be, but who are we really? That’s the main theme of this season."
"Things are going to get even more complicated, but that's the fun part of it," he teased.
Sunday's new episode will also see more fallout from the Teo (Juan Riedinger) situation, after the man from Javier's past confessed all to his sister, Ava (Maria Botto).
Now that they all know Teo's the one who killed Silk and was tasked by Javier's father with killing him too, what will the hitman do with him?
"As far as Teo is concerned, I can't elaborate too much as to what will happen to him so you'll have to keep watching," Botto said.
"Family has always been important to Javier and it still is," he continued. "He's trying so hard to be accepted by his sister again. You can expect this to continue to be a big part of this season."
"I was very happy that Maria came back after season one. The actress that plays her on the show is actually my sister," he added. "It's always a pleasure to work with her. I was thrilled to read that her character was back."
"Good Behavior" airs Sundays at 10pm on TNT.
