I know this seems off-topic, but actually, this really is (indirectly) related to the plot... well, you'll see why soon enough.
In the meantime, I believe Levana felt the only way she could make a few quick bucks, without having to travel by day, was babysitting.
As for "Furry Lesbian Gamers", that's not actually a real webcomic, but rather, it's an in-joke... don't even begin to try to understand.
POST-PRODUCTION EDIT/NOTE: I would like to stress that at the time I wrote and drew this strip, I was not aware of the existence of a Disney Channel show called My Babysitter's a Vampire, mainly because I've had no reason to watch Disney Channel in hundreds of years.
I wont go trying to hunt down 'Furry lesbian gamers' then. haha I did notice you have a remark on your personal page about vampire comics,sprite games and lesbian comics being too popular on here so I'm thinking that maybe this was an echo of that thought. hehe
