Okay, that's fair. Rey recalls her own mother, what had happened to her because she tried to protect a thing she created and called her child. She grimaces a moment, then glances back down to Rose.

"Well, guess I was different like you, too. Or, at least, I didn't 'work' like I was supposed to." She says that word with a bit of distaste. "So don't worry about it. Being different isn't so bad."

Considering that Rey isn't sure they would be friends (friends?) if Rose was the same as her kin.
