Among Connor's eccentricities is his perfect willingness and comfort to ride a skateboard around in the ARC in Season 2. You all remember, of course, when he skateboarded over to check on the anomaly detector?
It may be alright for one person to bring a skateboard into the building, but what if it didn't end there? What if Abby also decided to bring in a scooter?
Or what if Jenny Lewis biked into the building? No, it would never work if everyone acted like Connor. The poor ARC couldn't handle it.
