Sooooo is he Big Mac’s cousin or what? I mean, to be sure, a member of the Apple family dating a cousin doesn’t shock me, but very little of the Caramac stuff has an incestuous tone to it, so I then thought he was just some pony…and THEN I thought, “Why would he be working for the Apples if they have a pretty good handle on their end, esp. with any family members they could get?
My headcanon is that he harbored a crush on Applejack, but his incompetence just causes her to look down on him, and so he’s unable to bring out his feelings.
