Good Behavior wraps up its freshman run on Tuesday, and only ET has an exclusive sneak peek from the season finale.
In the clip, con artist Letty (Michelle Dockery) attempts to make a last-ditch effort to keep Javier (Juan Diego Botto), an expert killer, from making one last kill that could bring him six feet under.
“I thought you were done killing people? I thought you were done with this,” Letty asks, disapprovingly. “Whoever this person is, maybe they don’t deserve to die.”
“They do deserve to die,” Javier answers, not interested in continuing the conversation any further. “Letty, please. Go away.”
Easier said than done. When Javier goes into the store to pick up supplies, Letty proceeds to follow him through the aisles before she finds a moment to confront him about his dire plans and suggests he think about becoming a chef.
“You can actually cook really well -- professionally well,” Letty throws out, before Javier opens a large plastic container -- big enough to fit a dead body -- and asks, “Can you fit in this?” Watch the video above to see Letty’s reaction.
In November, Dockery spoke to ET about playing Letty, a recovering drug addict, con artist and mother to a young son.
“Letty by the end was different from maybe what I expected from the start,” Dockery said, adding that she was “conscious that Letty still shows through” via the various personas she inhabited.
Good Behavior airs its season finale on Tuesday at 9 p.m. ET/PT on TNT.
