Butt Heads

You and a crewmate just can't see eye to eye, and you need the others to mediate

Crowded

You can't catch a break on the ship, you wish the crew would just give you some space

Destruction

A crewmate is getting on your nerves, so you steal a sentimental item of theirs and destroy it

Hookup

In a moment of pique, hooking up with a crewmate seems like a good idea

Impostor

You keep making mistakes, maybe the crew would be better off without you

Isolation

The stars are so empty, you're starting to lose yourself in them

Pull Rank

You're the one that knows how to do this right, the crew should just listen to you

Triggered

Something has caused a deep-seated trauma or insecurity to flare up, the crew need to prop you up
