Yes, I think I mean foreshadowing/telegraphing his character and motivations. While the information is in his description, I would think of ways to hint at it in the rooms of the playhouse before the confrontation. Environmentally or otherwise, perhaps he communicates with the players via a tannoy or the shades are his avatars and whisper his secret desires while the dream larva mock him. I'm bad for over stuffing and the layout you've got is really good, I wouldn't want to spoil anything so do ignore me!
