Alexi flew into his office via the window. He came as fast as he could but there was a St.Mungo's epidemic a little more serious than anything that could happen at Hogwarts, other than werewolves and vampires becoming aggressive. However, it would be just plain and utter bad luck if something like that were to happen so Alexi ditched his post at the Hospital Wing and went to St.Mungo's. It was his job to understand the triage system, and that understanding was applied to the real world, not just the battlefield or in a hospital room.
Dropping his luggage, and not even changing out of his warmer clothing, Alexi walked into the hospital wing, to see carnage... and a couple of professors. "Bloody hell!" said Alexi. "And that can be interpreted literally! What happened?" Simultaneously, he accioed two vials of bone regrowing potions. "You both had better take them," said Alexi, giving them to Andrian and Jess. "Any more injured?" But Alexi wasted no time to pause. He assessed the situation and bone injuries weren't the only problem, there was a lot of blood loss. "Olesangui," said Alexi twice, once with his wand pointing at Jess, and once with his wand pointing at Andrian.
