"Oh!" is Klaudia's only real exclamation when that actually works, and the man drags himself bodily off the couch. It's definitely a start! And Wei Wuxian doesn't seem to mind that she's given their location away. Though how much she's actually given it away is up for debate, since Nie Huaisang is headed for the door instead.

Her companion is already banging on the window to add to her knocking, but just in case the man inside is having trouble hearing, Klaudia manifests a little Light magic of her own. On the door that Nie Huaisang is heading for (in true horror movie fashion) Klaudia writes an illusory "Behind You" in colors that flash contrary the strobe effect already going on. As someone desensitized to the horror genre in general, she's confident that this will be a very helpful directive.
