Cid smiles a bit at this,"It isn't really energy as much as need, the full form is a dragon, and apparently there has to bee a need, a current need for the form, and it is never able to be a selfish one," as he continues to try, knowing if you could find any one thing his new form would be required for, so long as it helps someone other than himself, someone he likes enough for it to count(which of course includes you) he would be able to enter it with the energy he has already from the gel below his feet.  By now you see the scales starting to spread, but his shape isn't really changing much, without that need it seems he might revert back to just wereaquatic form again.(repeats, only requirments are that he knows it will somehow benifit someone he would protect or be unable to harm on the full moon, that is when the full werewolf comes out.)
