Nero

He has trouble focusing and is always doing or up to something - including trouble.
He's one of Hart's oldest friends.
While some of his irresponsibility contributed to Hart dropping out of med school he never stopped supporting or encouraging his friend through thick and thin. He feels very guilty about any time he's ever felt at fault for something that happened to Hart and will sometimes do bold and unpredictable things to show Hart how determined he is to fix things. He was the only person able to track down where Hart went after "the incident" and show up unannounced.
He didn't have many high level skills to offer on the Ascent when he got there, but he managed to land a job moving and managing cargo. He can be very flirtatious.
