This may have already been determined, but if not, the person holding kiddie Rey on Jakku during her vision is indeed Unkar Plutt.
Kylo immediately thinks about Luke when talking about Rey. INTERESTING.
So, Han hasn't seen Kylo since he was in his teens (or thereabouts)?
Han touching Kylo's face apparently wasn't in the final script. Nice improv Harrison?
I wonder if Kylo's blade was originally intended to have more of a yellow-ish hue, then...
A mother's embrace, eh?
