this is dumb but is there like a portable TV or any way to get a TV where Dave is being kept.... can Maya valiantly try to unbrainwash him by playing him the Steel Samurai + providing occasional burgers?

also could she potentially like... mess with or prank Karsus a little, askin for a friend

Would reverse Necromantic Touch help with easing the pain/giving the sick enough strength to overcome the illness/poison?
