Unlike Connor and Bill, who had been scared silly by the young master, Joe had a different reaction. He'd been carefully observing the situation since he was so gently 'woken up' by the young master.
It was too late for them to plead innocence since they'd already committed the act, and there was no way that the young master was going to let them go just like that.
By now, Joe was more than familiar with the young master's thought process.
Compared to both Bill and Connor, Joe had been with the young master the longest, and he knew exactly how the young man ticked. He also had the best idea of what was going on in the young man's head even if he pretended not to.
Those that offended the young master never lived good lives, and Joe was all too aware of the fact.
Since he didn't want to die yet, then what he had to do was create a situation in order for all of them to live. Or at least, to let himself live.
