[It never actually happened like that. Stella designed the original power, and she was almost invariably teleporting to places where if there was anybody there she'd talked to them first. The kind of magic in question isn't very good at plain information - it can give different results contingent on facts but it's not so great at just having us know stuff unless we pick out a sensory modality and everything, and it didn't occur to her to have her superpower just stop working sometimes. Shell Bell figured the bathroom thing wasn't a problem because it doesn't land us near enough people we're looking for to land us in a small room. Then she had a close call with a Tony she was looking for who later informed her that he had a very large bathroom, she fixed it, by the time I met the peal it had been patched for a while.]
