The idea is to hunt down different pictures of Erica. The person above you will post a prompt about a picture with Erica in it, then you hunt down a picture that meets the prompt and ,finally, you post your own clue for the next person. Pictures can be from Smallville, candids, movies, photoshoots, etc.
Example: The person above you says:
Erica wearing glasses.
You post:
Then post the clue for the next person.
I'll start:
Erica wearing blue
