Hiro often makes main characters in logical disavantage against their opponent and come out on top, plus I don't think Juvia is weak to Ice Magic, she is able to make water boil if she gets angry, and Meredy is able to use her magic from far, if she shares a bond with the other party, she doesnt have be there.

And I don't think either Jellal, Laxus, Natsu or Gildarts will intervene in a fight involving Gruvia.. just sayin'

I am not saying this IS what is going to happen, but I think it'd be a Mashima-like development.
