Delivering coffee to Justin - a mediwizard Andrew was infrequently shagging - was never usually this dramatic. He'd been shepherded out of the building, coffee still in hand, to stand awkwardly with the gathering crowd of patients who'd been turfed out of their beds. Most people were watching the sky, straining to see if there was smoke billowing against the grey clouds. Andrew, on the other hand, was watching the door, waiting for someone official to come out and tell them it had been a mistake and they could all go back inside so he could finish his delivery, and his flirting.
So it was, that he spotted Melinda when she ran into the supposedly-burning building. Though he had seen little evidence that there was an actual fire, it still seemed to Andrew like the kind of brave-stupid thing only a Gryffindor would do. So, of course, he followed her. She was faster than he'd have expected, and he was still carrying hot coffee he didn't want to spill, so it took him a while to catch her up.
Just as he did, he saw a shrieking woman in a flowery nightdress aim her wand right in Melinda's path. Seconds later, Andrew had an armful of Melinda, the coffee was puddling on the floor and the patient was yelling at him to get her out. "I've got a bit of a problem here!" he shouted back at her. He curled his arm under Melinda's legs and lifted her up. "Alright, come with me then," he said to the old woman as he started to make his way back down the stairs.
