Also, since apparently Stephanie will be moving in, I presume that means she isn't happily romantically involved with anyone at the moment either, to which I say why don't you want these wonderful girls to have nice things.
(Side note: I also feel like someone is underestimating the appeal of Full House's original dynamic, a single dad w/ daughters vs. the current setup of a single mom with sons. Not least because girls are wonderful characters at all ages, and boys are usually the opposite of that. Also, and this may be the most important part, will they have a dog? Because Comet was clearly the star of that show, yet no one has mentioned such a thing even though they have time to mention hanger-on Kimmy Gibler.
I vote for blackmailing an Olsen into being the token single aunt, and making the house full because either DJ or Stephanie has a husband overseas (WHERE HE DOESN'T DIE) and/or are having some financial issues and decided it'd be less expensve to live together.
Once more hoping and praying that by the time Glee is old enough to have its characters dragged back into its existence, people are over the whole "super belated revival" craze.
