Dave is Ava Barlow's sex-fiend ex-boyfriend.
"who had a collection of pornography so big he could have opened his own store. And he called phone sex lines, like, a lot. Neither of these were bad things, as such. Except, phone bills over five hundred dollars month after month were a bit much. Not to mention, he wanted to have sex, like, twelve times a day, walked around naked at all times and tried to get me to go to swingers parties (um, no again)." - Ashley, Kristen (2011-04-24).
