[Nico's plan to be as boring as possible leads him here. A recital seems safe enough, anyway. And hey, he's even figured out how to direct his stupid viewer/camera/thing in other directions like Zatanna was trying to show him (that was her name, right?) so he can, like, pretend, he's here for the benefit of others.
It's really just accident that he's wound up near Trowa, but he does tend to drift near people he's met previously.]
