Re: EMP Reactions. Emmeline Vance Probably in her room. Mostly her reaction is "What now?" Then go about the ship to confirm with others on what's going on and taking the appropriate next step.
Violet Parr I'm not sure if she's with the other engineers or not, Tony asked her to be a judge, but I don't know if they check in on the projects or if that's for later. If the later, then I'm sure she'll be in the library. Obviously a little freaked out for a second, then looking to see what she needs to do to help.
