As for Leia and Chewie not consoling each other: I took as Chewie not realizing Leia already knew Han was dead. I thought maybe it was too difficult for Chewie to bring himself to tell her. Put yourself in Chewie’s shoes. If your best friend died, would it be easy for you to be the one to tell his/her spouse? As for Chewie taking off with Rey to find to Luke, I had no problem with it. Even with Han dead, Chewie would still want to do his duty.

That’s a good point actually. I just watched the film for the second time and I noticed that Chewie ran out of the Falcon following the medics that were carrying Finn. It wasn’t so much Chewie that ignored Leia, but rather Leia that ignored Chewie. She walked past him, and went for Rey. It’s a bit odd if you start to nitpick, but Rey is our protagonist, and Leia probably sensed her, as well as noticing how alone she looked. And she did know who she was, Finn and Han talked about her, and she couldn’t really have been anyone else.

btw, I never picked up that Obiwan was talking to Rey when she first picked up the lightsaber.

I noticed it this time around, but unless you’re looking for it you won’t have any clue that it’s actually Alec Guiness’ voice. It’s more of an Easter-egg I’d say.
