Corrected entry: During the final showdown Spike incapacitates Drusilla by choking her into unconsciousness. However, throughout Buffyverse material, especially on several occasions in Angel, it is pointed out specifically that this is impossible as vampires do not draw breath.Lord Mordo
Corrected entry: In Becoming Pt 2, Willow is in a coma due to head trauma, and hospitalized. I'm not a doctor, but wouldn't a coma patient in a hospital be hooked up to some machines, at least an IV? When she is shown in the hospital bed, she isn't hooked up to anything at all.
