Risa

Uh fuckin yikes o_o;

I personally would have tried to leverage the transporter and holodeck technologies

Just take her and the materials she merged with into the transport buffer, then load it into the holodeck to edit the snapshot, sort of like a surgery in frozen time, then try to flag the material that you can't be sure is human and organic to be "out of phase"

It won't be recoverable instantly. At best, the telefragged flesh can be collected into a bioslurry that can be regrown into replacements that can be subsequently reattached.

And, like, it looks like her critical organs are not telefragged at least...? Heart, lungs, brain, maybe liver and stomach at least partially?
