Samuel
I never loved nobody fully
This visit would be unexpected. He had picked up his supplies a week ago and wasn't due back for another two, but Samuel had come to a point where his duty required him to face uncomfortable personal matters. The search for Sunjata was stifled, desperate for any kind of valid information; he had no proof Nate was involved, but he knew the Doctor had his fingers in all kinds of pies - and that he was unlikely to turn away someone in need, which the Arbiter's son surely would be had he just left home.That, and he'd heard the clinic often harboured a information broker that could be useful, but finding actual information on that man had proven difficult.
Gently spitting rain pricked his face with cold little shocks as he stood outside the door, preparing himself to knock. It seemed conversations between him and Nate always became hostile. Maybe it was natural, the obvious relationship between an Enforcer (or close enough, anyway) and a criminal.
He knocked on the clinic door, glancing side to side to see if anyone was there to hear and look - no, he'd chosen the right hour. Early, likely when the Doctor was asleep, but that couldn't be helped. He'd knock until he was answered.
Always one foot on the ground
