I think that Tyki reacted to whatever is going on with Allen\14th and blacked out, like he did in the first Ark, breaking the window with sound wave - note how he is not cut at all, even though he is sitting in front of it.

Oh. I missed that panel, when reading. *facepalms* It can be the city that Ark is connected to, but it's far more likely that Noahs simply are in that skyscraper.
