So, they already know Rumple is back.

I wonder if Regina is going to tell them or how they will find out

(And I'm pleased to see they are already making the audience to rembember who Zelena is) either regina tells them. or hook and belle talk and hooks like "'what do you mean i haven't seen you in day" or something that causes them to deduce rumple's return.
