So far, Gary was not impressed.

He'd existed for less than a day and though grateful, was already bored. He eaten and taken and stroll with Flora, who he liked a lot, and Guy, who he was not so sure about. Gary didn't like Guy's mustache. He thought it was kind of pervy. Gary wasn't at all scared by Alan's appearance. Somebody owned the place, right?

Despite the fact that he was animal, magical, Gary was sentient and quite bright. He understood everything that was going on and everything that was said but he had no words.
Alan, as we will find, had many.
