let’s play a game called Why is Bones on the Bridge?

• an actual medical emergency
• he was bored
• he wanted to make sure Jim was behaving
• he needed his daily dose of argue with Spock time
• to see a first contact
• to show off his awesome juggling skills
• a pathogen that turns people blue has swept the ship and the bridge is the only place not contaminated
• to stab Jim with hypos
• to gossip
• he’s just there to look pretty
