Bc I saw a post that had TNG and DS9…
The TOS Triumvirate with mutant salamander babies
Jim: Loves them! Carries them around in an improvised baby sling. Tries to teach them warp theory. Ultimately accidently kills them.
McCoy: “Well, we can’t just abandon them, Spock!” Keeps them in a tank in the medbay. Grumbles about them to Jim at every opportunity. Happily talks at them when no one else is around. Chapel overhears, but saves the info for a special occasion.
Spock: is very dubious about this, but recognizes that leaving them behind would violate the Prime Directive. Does extensive research and sets up a habitat for them in his quarters. Plays Vulcan music for them. Absolutely does NOT talk to them about his hopeless crush on Jim.
Feel free to add more crew members!
