So it looks like Zoey was able to help the guys get rid of Drew... just not in the way they had intended.
The "smokin' hot blonde that lives up on the fifth floor" that Drew mentions is the same girl that we saw in the "A Zombie's Survival Guide" comic
Liquid Diet. When I drew that strip, I wanted to include a character that could be horrified at the predicament and none of the, at that time, current characters would do... afterward I didn't want to get rid of that character and I wanted to find a way to keep her in the comic.
To that end, I figured that I'd have Drew go live with her. Drew gets to live with a hot girl and Zombie Roomie gets another female cast member.
