Would it help to know Luz absolutely loved seeing her girlfriend turn red, even if Luz was very aware that Amity could make her do the same?

"I know, right? I was honestly a little scared I wouldn't ever see you after, well, coming here. Part of me knows I ought to be worried about all the things you've told me, and that I should be bothered you're trapped like I am."

Luz looked down, and yes, she turned red.

"But I could never feel trapped in any place if you're there with me."
