It happens so fast that Cassian doesn't anticipate it; one second Daryl has his hand around Ruby and the next there's blood everywhere, gushing from the alpha's nose and Cassian has to stop himself from cheering or growling. Instead, he shakes his head at the rest of the guards and puts himself between Ruby getting into the car and the now incensed alpha, raising an eyebrow at his coworkers and deciding, at that moment, that he's quitting this job.

It's cemented in his mind when he sees Mr. Williams coming towards the front stairs screaming his daughter's name just as Cassian shuts the rear car door behind him as the car pulls away from the house. He can still smell the blood in the air and his nostrils feel perpetually flared open, so he brings up a hand to pinch at the bridge of his nose.

It also helps to cover his growing smile, but not entirely, if we're being honest.

"You're a dangerous woman, Ruby Williams."
