When I first read the spoiler that all potentials were going to be slayerfied, I immediatly thought "Fred."
The Powers That Be need some serious recruitment on their side, since the end of the world is (well, constantly, but still: ) "near" so anything should go! (like a second vampire with a soul).
To go WAY off topic (I think):
In fact, as lame as many people think it would be, I think more vampires with souls are needed! Like the one who wanted to be pure before being sired: Dru (My favorite villian)... I think that would be an interesting story to play! (Personally, I think she would freak out and go all "I can't move") And if they did that, if Harmony (hey, I like her!) got a soul, don't you think that she would remain the EXACT same, no guilty concience or anything? "So I killed some people. I'm a vampire. It's what I do!" And if they played both story lines at the same time, you've got yourself some good TV (in my opinion). [/off topic thoughts]
And I'm new. If off topic is bad in a thread, just let me know!
