Why can't she go with someone?

I like to give her some solo time in that way. Plus, it's a bit of an embarassment when walking out with those of the opposite gender, especially since Anedine has only made one female friend so far out of three (cue possible reverse harem) and it's likely that Cortez doesn't like walking out with people for errands.

But if you really want crazy stuff like that, let that rule stay.
