"Yeah, kinda like a bird," Eren says. Flying is flying, right? It does always seem birdlike to him, though impossibly large. The airships aren't quite like the ones they had at home (probably because magic), though of course Marco never knew about those either. Eren won't get into that now.

"I can fly one," he answers. "So...sure, we can try one."

Eren isn't the world's best pilot or anything but he knows enough to not get them into danger or dead. He enjoys Marco's enjoyment, even if he still doesn't smile himself. He fields whatever questions Marco has as much as he can, though his technical expertise is severely lacking and sometimes all he can do is shrug. It's a good way to see the city from the air though!
