I was wondering if part of having that Oathbreaker Ghosty hanging out with Skelly is to test out those juicy backstories for custom-made characters that Larian promised, and add an additional layer to their character progression. Paladins get Oathbreaker, Warlocks get their patron to pop up, Clerics an avatar of their deity, Bards are stuck with Volo / Alfira to learn / acquire new tricks, Rogues get someone from the Zhent to keep an eye on them....
It would be odd that Paladin is the only class that gets a "special camp counselor".
