Okay, when I saw @LinkScratchStar project about maybe Mcmuffins being the good guy, I knew I had to share this. So in a lot of TOPH theme songs we see Dave reaching out to Perfectpaw, right, and Perfectpaw is either falling or mad. So I was thinking, maybe Dave goes to the Gathering and sees his son and daughter there, and he decides that he is going to visit ShadowClan to see his mate and reconnect with his family. While Dave is gone, Perfectpaw falls back into his old ways. He becomes the attention seeking brat that he used to be. I'm not sure how yet, but Perfectpaw meets Mcmuffins again, and she starts mentoring him, probably because he wants to get revenge on someone. Why, I don't know, but just bear with me. She takes him under her wing (paw?) and trains him in fighting and pretty much being terrible. Now, in the first story board Mcmuffins ruffles his fur. I think this is because as they train together she gets closer to Perfectpaw, and begins to change for the better. However, when Dave finds out he does not believe that she changed. He finally believes that she has changed when Perfectpaw get hurt and she brings him back, as seen in one of Ranboo's projects (I forget which one) That's it for my theory today, please feel free to add on to this in the comments!
