Tara (contains spoilers if you haven't seen episode 10)

Well, considering that the whole exorcism thing was fake, why is it that Tara saw the blood on the uh.. stake? Or whatever it was. Were the meds messing with her mind so much that she could see "physical" evidence?

Episode 10

I can't find a working link. Any suggestions all of them seem to be broken. HELP please I can't wait any longer lol. Thanks in advance for any help.
