Lisa Fary is a graduate of the creative writing program at Florida State University and holds an advanced degree in Special Education. Her earliest influences are Princess Leia, Rainbow Bright, Astronaut Barbie, and her 6th grade teacher, Ms. Palmer. She’s angry that it’s almost 2010 and she still doesn’t have a hovercraft, but will accept a jetpack as consolation. That jetpack had better be pink with a rhinestone monogram.

"So… don't you think you should move on?" LOLZ! "You are my candy-beard." Great!
Yeah, when I saw this on Monday, I squeed with so much glee!
I love Castle, period – it's a police procedural for English nerds, after all – but this ep made me love it more.
And he still looks amazing in a brown coat.
Ack! My heart! It exploded from the awesome!
I've watched the first five minutes four times already. Mal costume, Buffy reference, and a Dickens reference. So fun!
Also, Fillion revealed on Twitter that he swiped the catalyzer from 'Out of Gas' and put it in Castle's living room bookshelf beneath the model boat. It's hard to see, but it's there. Easter egg'd!
