It would be silly to get careless, even here. That doesn't mean they can't acknowledge that so far, this world had less dangers than their own on a regular day. Just the fact that they're wanted, celebrated here makes a huge difference.

Still, Levi can't help but find similarities, as well. A looming threat in the distance, held back only by a barrier...

Well. There's no need to poison the present with what may be. They'll deal with calamities once they come. For now, it's a nice reassurance. Even if Levi isn't at Erwin's side the moment he runs into trouble, the man won't be defenseless.

There's a small pause as Levi takes Jean's words in, thinks about them. It makes sense, then, he thinks, that someone with a gentle heart would enjoy having the chance to create something. Soldiers usually destroyed, even when their reasons were good.

Maybe, if their world had been less shitty, this is something Jean would have done from the start, instead of trying to seek safety for his family through the military and experiencing enough horrors to get roped in for real.
