Ellen's not really as familiar with either Curtis or Edgar as she might like, but that's no reason to leave them unchecked-on after what they've been through. The doctor gets first go, of course. Medical care is an important thing, and the doctors here know what they're doing.

(Dad wouldn't be pleased with her if she interfered with medical treatment after an emergency. There's that too.)

Anyway, she went upstairs as soon as the doctors took the handoff and changed out of that stealth suit of hers, so when Edgar sees her fidgeting a little ways away from the cot, she's in her old, many-times-patched, many-times-reinforced Vault suit of faded blue and yellow-gold and offering a small, worried smile.
