Without Crozier realizing it, Hickey's thinking of the same thing. Neptune. Crozier loved that stupid dog, shitting and shedding all over the place. Really, Hickey couldn't stand it. The most useful thing Neptune did was meet his end. But that was a proper dog, not a man pretending to be a wolf pretending to be a dog. Maybe that's what strategy he'll take.

Crozier's voice gives him the opportunity to take that strategy. Hickey turns his attention over to Crozier. Right, time to act as Neptune, you can do this. Pretended to be Cornelius Hickey for a few bloody years, he could easily be a dog for an hour or so. Hickey sticks out his tongue, starts wagging his tail, and shifts his expression to a big, stupid, brainless expression.

Come on, mate. He's just happy to see you! Reward him with your love and affection and letting him inside the house.
