Alicia built up a rant in her head about all the reasons she was the worst person to call when you were sick. She wasn't patient, she wasn't gentle but she also rarely got grossed out. Considering how she went off on his brother in public (which he completely deserves) she figured she could do this without too much complaining. It wasn't his fault his brother was a twat.
She wasn't an idiot. She transfigured herself a surgical mask, knowing she couldn't afford to miss any more work. She was barely making rent as is. She let herself in, figuring he probably wasn't in a state to answer the door. She had orange juice, crackers and soup in a bag. If that didn't help then tough luck.
"Merlin, you look like the giant squid. It's a good thing you don't have a bird, she'd be running away screaming." She made her way over to the couch, messing up his hair and she quickly touched his forehead. Damn, he really was sick.
