Ena wasn't expecting to take some of the damage of her own spell in return. Ow. Luckily her resistance to ice mitigated some of that, but...you know.

Nor was she expecting the blast. Ow.

When she hears Kanji announcing he was about to target her, she gathers herself quickly enough to understand her instinct to cast Fly on herself, launching herself a good twenty or so feet into the air and hopefully out of the way.

But she then looks down to Sephiroth. She couldn't abandon him from the skies--she knew how that went last time...

The ice storm still rages.
