Quote #1
KYLO REN: You know what I've come for.
LOR SAN TEKKA: I know where you come from. Before you called yourself Kylo Ren.
KYLO REN: The map to Skywalker. We know you've found it, and now you're going to give it to the First Order.
LOR SAN TEKKA: The First Order rose from the dark side...you did not.
KYLO REN: I'll show you the dark side.
LOR SAN TEKKA: You may try, but you cannot deny the truth that is your family.
Family isn't something you can walk away from. Okay, it is, but there's going to be consequences if you do. Lor is letting Kylo Ren know that he may wish to separate himself from his family, but they may have other ideas…and if he's not careful, that's going to muck up the whole Dark Lord of the Sith thing he's trying to get going.

REY: Don't give up. He still might show up. Whoever it is you're waiting for. Classified. I know all about waiting. For my family. They'll be back. One day.
This is Rey's defining trait early in the film. She waits for a long-lost family, hoping they'll come for her. They're not. Seriously, like ever. But that hope is all she has. It's what defines her…at least until a better option comes along.
Quote #3
MAZ: Whomever you're waiting for on Jakku, they're never coming back. But...there's someone who still could.
REY: Luke.
Regardless of who Rey's family really turns out to be, Luke is, in essence, her spiritual family: the guy who can give her that sense of belonging that she's missed and help guide her on the right path.
