That's a pretty big plot hole that many seem to overlook. Logically speaking, it doesn't make any sense that Yuri and Evan knew an Irregular was entering the Tower. I haven't seen anything anywhere that explains how she knew either.

Then again, if Yuri hadn't been there, the story pretty much would have ended instantly with Baam being killed by the White Steel Eel. When you think about it, Yuri is like a walking Deus Ex Machina; every time the situation looks lost, Yuri appears to save the day.
