Original Description:
 
“My word, what the heck- oh, oh dear, if this gas is what I think it is…”
 
After a bit of shuffling to get herself out from under the nose of the bomb, Tavi couldn’t help but take in a big gasp from all the sudden movements, and naturally that led her to getting quite a good lungful of that fwhoomp-inducing gas lingering all around the burst site! And with her being right at the epicenter, it’s a bit of a sprint for her to try and run her way free… but on the rather literal upside, P-235 is a very dense gas, so as long as she gets above it somehow she’ll be free - and a bit of that very same gas is all it takes to get her floaty enough for that~
