Murder was a human thing that animals sometimes partook in when there was a good reason for it.
Werewolf instincts were something that Bane couldn't ignore. He had been doing his best to avoid Celeste, but Divo was starting to get impatient with him and was not going to allow it to go on for much longer.
The stupid wolf was ignoring everything that he had been trying to put into place just for a few minutes of being able to see the little human even if they weren't going to be interacting. How his human side detested when his animal instincts took over.
There was someplace else that he needed to be at the current moment in time that the wolf was ignoring for something like this.
If it was something work-related, he wouldn't have minded putting it off but this was something far more important than that which he couldn't put off.
