Fred: you're seriously insane! At least they weren't locked in boxes with hungry beasts! 

Randa: *shakes head* yeah, I don't think he is either. *looks at Fred* you know, for as much as you pride yourself on animal taming, you really butch out at the last minute.

Fred: Siren! I thought you said she couldn't lock me in here.

Technically, she didn't. Garret did, and I can't technically tell him not to. 

Lia: *smiles* only a little 

Ez: *nods* that makes sense.
