my heart broke for drake bell watching that. the fact that his mother knew, that he told her what was happening and she ignored it (while his girlfriend’s mother picked up on it almost instantly) was awful. that whole generation of kids, including ariana grande, must carry so much. that’s not even mentioning amanda bynes, and i still don’t think we’ll ever know the full story of what happened to her.
i know a lot of people have theorised similar to you about leo (with the context of his adult romantic relationships too). he does have a very strong mother, who was around him a lot, but she obviously couldn’t be there all the time.
