Luka: I've got a feeling it's our communication problem.
Abby: (nods) Well, if you're not sure... it probably is. (Luka nods) Sorry. Uh, if you want to talk about it-
Luka: No. I mean, if I wanted to talk about it, Sam probably wouldn't be moving out.
Abby:...Thanks, Luka. (Luka gives her a puzzled look) I always thought it was my fault things didn't work out between us (Luka starts to grin)...but, now I know it was you.
