It depends on why she turned into a bat. I don't think Twilight's spell (which was to alter the bats' minds) should have made her change physically. That was evidence of somepony else using a transformation spell on Fluttershy. So, maybe, under the right circumstances, it could happen again.

If it is the act of another magic user, then the end of the season, where they usually confront some sort of villian, would be the time we learn who it was and why they did it.
