Signs

[porpoise]

In her palm she held Fire 
in a form she controlled => i assume that if she can hold it, she can control it? a possible redundancy?
so all could see, but none
could touch.

He, enamored by her energy
tried to touch but was burned. => you've already said no one could touch it - so how does he? or is it that no one is allowed to touch?
In his hand held Water however,
so the burn was quick to cease. => i feel that this line could be better worded - how does he get burnt if he has water in the same hand? and I would drop 'cease' and replace it with 'quit' or a similar word

Curiously, she gave him her hand. => not a fan of 'curiously' - why is this action such a mystery?
He doused her brightness, => maybe 'doused her flame'? i don't think douse and the idea of light really mesh well.
but she grew stronger in form.
Finally, she exploded; => this is a mysterious choice of punctuation.

He, without form. => these two lines tickle me in some kind of way. i feel that one line or both lines without so much punctuation would emphasize the "formlessness" of the two.
She, without form.

Thanks for sharing.
