Supernatural is up to its old bag of tricks again.

In season 1, there were two guest stars who were well-known to all Buffy and Angel fans - Julie Benz and Amy Acker.

I just watched an episode in season 3 and they brought in Mercedes McNab. The funny thing is she played a vampire who didn't know she had been turned.

I find it amusing.

Now, if only David Boreanaz or Sarah Michelle Gellar would show up. Or even any of the others.

But I'm almost sure they won't. Most people take Supernatural for granted.
