I don't think it's a cure, degrimm. I think we're being shown the ominous side of the stick. Overwhelming a valuable asset while they're fleeing from the enemy is not a cure. It puts the scoobies into a very dangerous situation. While Nick has temporarily held off BC, that doesn't mean more aren't on the way. They needed Eve to help them, to guard them. They no long have that because she has effectively been crippled.
The best way to frustrate a cyberbully is to ignore him.
