Erin has managed to do what Hawkeye could not: First Aid slowly lets his face sink into his open palms.

"I'm glad at least one of us is happy," he says blankly, staring straight down the barrel at his worst localized fear: pandemic conditions.

"...Okay." He pulls a deep draught of air through his vents and raises his head, squaring his shoulders. "I'd like you to come back and see me as soon as you start feeling unwell, okay? And please tell everyone else who was in that world with you. It's too late to prevent a possible infection, but we have medicine that can treat the symptoms and help you stay comfortable while you recuperate."

He may need to discuss the construction of a quarantine ward with the mayor. Or would that be an issue for the Safety Committee? He'll ask Miss Breugaire if he sees her.
