So if you’ve seen today’s episode (it was pretty good), it has lots of interactions including Rumble, which is good for anyone that ships him with a member of the CMCs. And I headcanon that since he didn’t get his CM in the episode, he didn’t get it at the camp at all, and earned it some other way later on, still thanks to the CMC, more specifically Scootaloo. So he feels the need to repay her…
