"Gilgamesh go walkabout & father [come back{a scary clank]lady} wants to fix a new body in a tank making a new brain to put brain in a tank body in a big lab. It's going to work & then [s]he's in command of the whole ship & empire & everything. It's bad"

Uncertain whether it's "father come back a scary clank, lady wants to fix..." or "father come back, a scary clank lady wants to fix..." Could be either & both are terrifying.

Agree, my first thoughts went to Madame Olga's body in Klaus's lab.
