[ They haven't gotten into all that much trouble together, but Cisco's seen Rey's ferocious streak. He knows how protective she can be, how righteously angry, in the right circumstances. She'd come from a world where niceness, softness, almost always was punished, and still there was some part of her that wanted to look out for others. It was pretty remarkable. Cisco casts a quick glance over to where Rey is, smiling. ]

Well, I'm glad you worked it out in the end. First impressions are bullshit, anyway.
