Jesper does manage to keep quiet when Inej gets closer, she is very quiet after all and if anyone could catch with her hands, it would be her. His cage is too loud to be able to just close it in around a pigeon, better if she can snag it and then throw it into the cage. He is waiting with it behind her, watchful. It shouldn't be that surprising that an animal is a little more sensitive to human movement than other humans, and the pigeon floats over Inej's head.

"It might be," Jesper laughs, now that the jig is up and the pigeon sees them. But it zips from her right past him, and flies down the other side of the roof. "Oh you think you're so clever!" And just like that, he runs right after it, definitely not bothering to be quiet now. In true Jesper fashion he is not really thinking through his choices, he's running after it, eyes on the prize, his instincts helping him to sail over one or two roofs successfully.

But he is no Inej, and he also hasn't learned that not everything here has easy rooftops the way Ketterdam does. He knows that, logically, but when he was moving, he didn't think about it. So he jumps from one and expects another to be at the leap, and instead there's nothing but air. For a few seconds Jesper seems to be in free range air and flails, crashing down toward the ground with a very inelegant and not at all badass squeak.

Luckily for him, he was only moderately high when it happened and he has the type of innate skill that has him rolling as soon as he hits the ground. Except his cage slams to the ground when he does and he rolls into it, banging his forehead against it.

There are people looking and Jesper lies on his back, glancing up toward where he just was, and Inej may still be. "Ow."
