Wouldn’t surprise me. He’s always had a weird fixation on childhood and the idea of being a child - AM has always felt uncomfortable for that very reason. Stephie and Ciel give this vibe of being what Labelle wants to be: children but able to engage in adult discourse and activities (remember Ciel’s “We had a sex!” strip?).
Labelle has spent his entire career playing down his age and now he’s reached the stage where he simply cannot deny the ageing process, the idea that he is an adult. Anyone who sees him in real life knows how old he is and any long-term follower knows he’s not in his early twenties.
It makes a certain amount of sense that he’d retreat even further into the fantasy in response. Ultimately, this is what happens when you don’t monitor your 13-year-old son online and he gets molested.
