I think TTH needs more femslash, so how about crossing Buffy and Fringe?

Buffy/Olivia

Post Chosen, and the comics can be canon if you wish.

Only other potential pairings should be Willow/Astrid and Dawn/Peter. Perhaps, in the past, Giles and Walter knew each other.

Olivia somehow finds out about an organization called "The Watchers Council" and is concerned that they may be a cause of some of the random experiments known as "the pattern". While investigating, she discovers that while not part of the pattern, the watchers councils operatives are also invest...

And perhaps something outside the norm, so here is the challenge.

BtVS and The Big Bang Theory cross so that Willow Meets Penny!

Some things I would like to see...

1. Post Chosen, Willow is part of new Watchers Council. You can use season 8 comics as well if you like.

2. Penny is activated as a Slayer, Willow shows up to recruit her and falls for her. Penny, for the first time, is immediately attracted to a woman but doesn't know how to proceed...

3. Leonard or Sheldon finds out somehow and recruit Howard and Rajesh to help their new super her...
