Yeah we were going to give her two perhaps three, but the two would wear off and she'd keep her original element I think. I think she'd be fire at heart, then given water and later air but that could be too much for her to handle, thus she ends up losing it and rejects more experiments and drugs, which would be when Team Avatar makes their move. We were also going to have Meelo die, if I recall, which could be where the air element came from. We also still wanted Tenzin and Lin and Jinora changing ages or...?
