Cyd: That's our superpower. Our friendship.

Shelby: That is the cheesiest thing either of us has ever said, and it came out of YOUR mouth.

Cyd: I'm serious. When the whole world was against us...Janet had our friends...your dad didn't believe us - we didn't even have our powers...we had each other. I couldn't have done any of this stuff without you.

Shelby: I never could've done any of this stuff without you.

Cyd: And you'll never have to.
