Looks like she hasn't gotten all the body wide flinches out of her system just yet. Something about that voice draws a harsh jolt out of her... But it also forces Tifa to bolt upright, even as a chunk of upper plate (or is it a house-? Does it matter, beyond being a crushing weight?) comes rushing down.

She has to roll away, to avoid getting crushed. The impact still rattles her teeth, even as Tifa forces herself to stand. The person she was trying to help... They're gone. Dissolved away the second she took her eyes off them.

Not that there's any time to grieve or get confused. She's pretty sure that she heard-

"...Zack?"

Her brain is a roil right now. Can't settle on anger or fear or tears. Tifa puts that decision off for a little longer as she runs to the fire and wreckage. Not sure if she can jump it yet, though she's certainly ready to try. But first, better call out to him.

"Are you okay!? Are you hurt!?"
