Jean turns out to be a rather plain (if hard-eyed) pegasus pony with a somewhat familiar cutie mark. And while he's a pony now, he doesn't have any knowledge of magic, so he doesn't feel or notice any difference. So he goes about the sort of stuff he would normally be up to in a day.

Namely, he's set up a load Titan training dummies on the checkerboard hills. Sword in mouth, he makes quick, precise dives at the targets on the dummies' necks, slashing them open at a very particular point and angle. After he finishes each dive, he stops to examine his work, to see how well he did, and then winds up and tries again.

One small thing he does notice is that this seems... too easy. Didn't this used to be harder? This whole flying thing? He didn't used to be able to go in any direction like this, unfettered by gravity. Maybe he's just gotten really good at it, after so much training.

That was probably it. He was just that amazing. His only regret is that there isn't anyone from his world here to praise him on his work. This isn't nearly as enjoyable without anyone around to pat him on the metaphorical back. He subsists on the praise of strangers.

Ah well. If any Titans were ever to come to Wonderland, he was confident now that he could take them all on himself!
