I want to scan the people that are floating, and some of the people with headaches as well. It's completely non-invasive, I don't need to touch anyone or get samples or anything like that. Lyla scans them and the area around them, that's all.
I want to scan them to see if there's any trace of something that's Vecna and not them, and then it'll be something else to help locate him/Eddie. Energy signatures, some weird trace element or compound, something that shows up this link he's established that can be disrupted by songs. Then again, there may be nothing there, I don't know.
The people floating can't give consent, though, and I've had to deal with entirely too much red tape before now, so I guess I'm asking for consent from their Next of Kin to do these scans.
[Edit] Monsieur Clairmont, do I have your permission to visit Ms. Eponine Thenardier at your home?
