Things seemed to be developing quickly. Lou couldn't even keep track of how many of the creatures were loose, as another had just run by his feet clutching a button. Scamander was apparently after it, so Lou deftly moved out of the way and instead focused his attention on a second niffler who had started climbing up the door-post of a shop across the street. He shot a stunning spell at the creature — but failed to realize that someone else was running by and stepped directly into the path of his spell.

"Er! Sorry!" he called, hoping they ducked.
