There's no trouble, per se. There are people who seem to be looking around, like tourists. There's a man headed toward the ticket counter with red sunglasses, a Chinese young woman in a yellow coat chattering away at him. He steps past Rachel, with a soft 'excuse me' and steps up to the ticket counter, asking about prices.

It's a busy day in Grand Central, but when isn't it? It's called 'Grand Central' for a reason. Kevin's hanging out near the door when he turns and thinks he sees someone he recognizes. He's paranoid for a reason, and that paranoia pays off, when he spies the yellow coat.

"RUN!" He yells, and then all hell breaks loose. A statuesque black woman breaks away from the crowd and races toward Kevin. The man in red sunglasses lunges for Rachel and fireworks explode into the air. Then, people with earwigs in start running toward her and toward Kevin. Kevin flattens one with a garbage can upside the head. When Rachel gets to him at the door, he grabs her hand and runs. Suddenly there are black SUVs everywhere and men and women in uniforms. Kevin dodges around a group, suddenly stopping and dropping allowing an electrified net to go sailing over their heads.

The insignia on the door of the SUVs is well known: SHIELD. The individuals with powers? Why those would be the X-Men, trying to get back one of their students.
