If she tries to put the Flight Ring on his right hand, she may find (if she hasn't noticed before), that Maugris is actually missing his ring finger on that hand. Thankfully, he still has nine perfectly good fingers, if slightly larger ones than Phantom Girl's.

In any case, 31st century antigravity technology works something indistinguishable from magic, and Maugris's unconscious form is indeed perfectly light and easy to transport. She may or may not also spot his sword lying in the road a little distance away; he'd probably be grateful if she brought that along, but if not he'll just have to come back for it later and hope no one's pinched it.
