Mikey's mouth was in the middle of forming a vehement no to that question when his brain caught up and he realised Nate was joking. He chuckled quietly and then took a step back in case Nate's shrugging was going to send his wings sprawling out sideways. "Easily reversible, hmm, yeah, I probably did say that, didn't I." Good thing there hadn't been any paperwork or anything.
"It might reverse back properly if I did it a second time," he said, waggling an eyebrow at Nate amusedly. "But on the other hand, you might come back with a beak as well." Or tufts of feathers poking out from odd places. "We'd have to feed you on birdseed and teach you how to tap morse code." And then there really would be Howlers from friends and family.
He was going to elaborate along those lines - a language of squawks, perhaps? - but then the wings started to open up and instead he had to work on holding back his urge to reach out and try and measure the wings so he could start working on ratios.
