Nobody else is having any other things happening to them that we know of, [ Hilbert points out, as he starts to tie the tourniquet around Vash's upper arm. ] Entirely possible that someone else has changed, but has not changed in public way.

[ As he works, it's obvious Hilbert's idea of a bedside manner is nearly nonexistent. He swabs the bend of Vash's arm without giving the man a heads up: enjoy the sensation of cold alcohol. ]

I have had similarities between memories obtained, but nothing that has progressed beyond mental state.
