mcspirk; kirk/bones/spock

who holds the umbrella when it rains: KIRK (at first). BONES WOULD BUT JIM JUST SORTA LOOKS AT HIM WITH THIS PATRONIZING CAPTAIN FACE UNTIL SPOCK ACTS LIKE A GROWNUP AND SEPERATES THEM BY INSERTING HIMSELF IN BETWEEN THEM AND TAKING THE UMBRELLA (he's the tallest of the three so it works out best this way anyway)

who is the grumpiest in the morning: Bones is always grumpy but like Spock before he has fulfilled an average of six hours of rest is a vindictive asshole (for a Vulcan at least). Do not, under any circumstances interrupt the First Officer's sleep, dammit. Just don't.

who worries more when the other is sick/hurt: Bones is a worrywart. Space is awful and dangerous and he'd know best because he sees it all down in Medbay.

who plays pranks on the other: Kirk ofc. Who else?

who is always the first to suggest cuddling on the sofa: It just sort of happens. Spock will sit down and Jim will curl into one side and while Bones sort of starts out on the opposite end of the couch he will inevitably end up curled up next to Spock who is growing used to that sort of spoiling 

who insists on creating nicknames for the other: Bones still calls Spock "Hobgoblin" in public, but...I'm not sure that's what you had in mind....

who drools on the other when they’re asleep: Bones drools horribly, though Jim isn't much better.
