The restaurant was busy, but not crowded to the point of irritation. The was no line up in the bathroom or anything, and he was smiling to himself when he pushed the door open and went inside, but boy did that fail on his lips as soon as he got in there. No one else was in there and only one cubicle was occupied. Blaine was in the bathroom all of ten seconds and was about to call out to Kurt when there was the unmistakable sounds of exerted vomiting from that cubicle. Still, just in case he was mistake, he still for a moment, listening and then the person inside retched again and that tell-tale sound of wet hitting wet left no room for error.

It wasn't a small bathroom, but there was no one else in there and Blaine quickly and succinctly put two and two together. "Kurt?!" he cried, moving over to the close bathroom stall. He gave it a soft knock. "Kurt, it's Blaine. Are you okay, sweetheart? That is Kurt, right? Did the pizza make you sick? Kurt, open the door and I'll get you some wet towels for your face... Kurt?"

The choked heaving continued for a couple of moments more and when no real answer to his queries came, Blaine started to wonder if it was even Kurt in there. But he had seen Kurt come in the direction of the bathrooms just a few moments before him and the restaurant had no back entrance. It had to be his boyfriend in there but Kurt had seemed fine just before? If he wasn't feeling well, why didn't he tell Blaine that? Confusion reigned free then, only to hear some shuffling through the cubicle door. Something being crumpled... a toilet seat cover? Who used one of those to spew? If Blaine was nauseated, he never had time to think about something like use a cover. And then the flush, and he stepped back a little to wait for the door to open.
