Some interesting tidbits here about the TFA supportive characters;

It doesn't give much important new info however; except that the "Unkar's thugs" previously mentioned works for a junk dealer called Unkar Plutt, and that the Kanjiklub gang lead by Tasu Leech is apparently an "intergalactic criminal organization."

This seems different than the trailers have led us to believe:

"BB-8 is the spherical, loyal Astromech Droid of the Resistance pilot Poe Dameron."
