Also, made a looong list in the last UK thread of all the possible Harry Potter stuff-- one of the things was a blood-strengthening potion; maybe technology can do stuff too?

Also, I don't know if Nat's mentioned this, but FK canon has vamps being effected by curare and strychnine to help stop and start the heart. She may want to have to do some nasty things to Angel to keep him hanging in there.
