I went and checked the episode again. No good, its all too much flash flash boom boom, can't tell.
I'm really looking forward to next episode now. If there's a problem with Natsus play I'm kind of expecting them to keep it hidden for a while, but the training session announced in the preview should be
informative 
And as for the VA for Natsu, none of the usual sources I check for this have it either KiNA.
Who's Dori's VA btw?
