[Angel/Supernatural] How do Sam and Dean handle Angelus?

So Sam and Dean get transported to the Buffyverse. Angel has lost his soul and Angelus knows enough about Sam and Dean to play his typical mind games with them. Would they be able to stop him?

In short: probably not.

Sam and Dean Winchester are used to dealing with vampires only slightly stronger than normal humans and, well, Moose is stronger than most normal humans.

But in the Buffyverse, vampires are superbeings in comparison to humans. The only humans who fights vampires without the help of paramilitary assistance are The Slayers, who are physically a match for vampires and other forms of demons.

Angelus could physically fight and kill both Sam and Dean without much difficulty. Add to that the mental torment he loves to unleash as he toys with his prey, and the outcome is all but certain.

That said, Sam and Dean are resourceful and have been underestimated before, so there's always a chance...
