The voice was less shocking than the figure it came from.  Arthur turned towards the source of it, confused by the cadence, only to look up and up and up towards the bearded face of an absolute giant of a man.  Lord, have mercy.  Arthur would never get used to being in this mans presence.

"Mr. Volkova," Arthur greeted, squinting up at the man, only to amend a second later, "Alexi, how nice to see you!"

How to explain his injuries.

"This is just - some argument or another with a patient of mine," he said with the wave of a hand.  "Don't let it concern you, I promise I'm just fine.  You should see my shoulder!  In a much worse state, but!  Ah, enough about me, how are you?  It's been a while."

Arthur's own green eyes could just barely make out Alexi's blue ones.  The doctor could feel something off about the man, but he couldn't put his finger on it.
