Crystal is really struggling mentally, but represses everything in favour of supporting and protecting the other mutants. She has particularly deep-rooted issues surrounding what happened to her family, and certain things will cause this to resurface. Getting through the crystal caves was… Not a fun time for her. 

Fish, being a close friend, is the only one so far to have asked her if she’s okay. She let on a tiny bit before changing the subject completely.

Ironically enough she’s the one telling the others how unhealthy it is to bottle things up, and is more than happy to lend an ear if they need to talk anything out.
