Blackjack's Links
Blackjack considers Chip as his only friend. The only creature that has been able to put up with his grumpiness and lack of happiness. He isn't sure what he would do without Chip in his life. Things would be very different, and Blackjack would probably talk more to himself. He's very thankful to have Chip around.
How Chip has managed to stay with Blackjack for so long, he cannot answer. But there's something about the grumpy foxpond that makes Chip want to stay. He feels a need to be Blackjack's friend. After all, if he wasn't, who would be? The puddlox, overall, enjoys Blackjack's company, even if it means sitting in silence for hours on end.
