Are Jack and Renee together? That's what my dad сказал(-а) after the last episode. But I'm not sure.

Unofficially, yes they are.

i don't think they are yet. i am probably wrong though.

Well, they've established that they want to be together, but they hanven't actually seen each other since сказал(-а) phone conversation so, to make a long story short, I've been wondering the same thing.
