Shakespeare didn't like Cascade, the boy didn't like Valentine much either for that matter. Perhaps the main problem was simply that he was here against his will, parted from his parents for reasons he still couldn't quite understand. Caesar wasn't much help, asking all the wrong questions in his opinion and poor Colette would openly express the sorrow that Shakespeare kept bottled up and hidden away from their captors.
There were other children as well that he now had to put up with. They too were three siblings though unlike Shakespeare and his litter, belonged here in this den. Cascade was their mother and this Valentine their father. Was Valentine not happy with the three children he had though that he had to go and take more? He couldn't make sense of it, nor did he want to. He just wanted Valentine to let them go back their parents.
The boy had developed a bit of a knack for quietly sneaking out of the den during chaos even when it had been simply his family, not these strangers. Whilst he didn't really want to leave Colette alone, he'd abuse the capability now, venturing outside and travelling a short distance from the den. He longed to continue all the way, race back to his parents though he wouldn't stray that far from his sister or even Caesar. Whilst the boy seemed to be coping a lot better, Shakespeare honestly felt that the entire family ought to be together. These people were not his family nor would they ever be.
