Main Characters in this Episode
Gavin: She's hiding the woman I was sent back to kill.
Prue Halliwell: Sent back from where?
Gavin: The future. What are you doing...
Prue Halliwell: Why kill Tanya?
Gavin: I don't want Tanya. I want... what's inside her. No!
Prue Halliwell: And the others, why kill them?
Gavin: They were all... pieces of the puzzle... pieces of the vaccine. Stop this!
Inspector Andy Trudeau: If I have to answer right now I don't think so, Prue. I mean, there's nothing wrong with it, I guess. It's just not a future I envision having.
Prue Halliwell: What's the vaccine for? What does it protect against?
Gavin: Against me, of course and all other warlocks like me in the future. The Parker child will be the one to bring together all the elements to create the vaccine which will destroy us.
- Goof (revealing mistake): When the Warlock Gavin kills one of the effects shown is the eyes drained of color, this is confirmed by Andy (at around 46 mins), however when the corpse of the first victim is found (at around 13 mins) the eyes were shown as normal.
