Basically, what it is, is one person says a quote from the series, then the next person has to guess which character said it. That person then says another quote, and so on.

For example (this is from another series):

"To love is to destroy."

Jace
"I always thought it was good things come to those who do the wave."

Simon...
Etc.

Okay, I'll start.

"No. I won't leave Ethan with a bunch of monsters. I've lost a father already - I won't lose a brother as well."
