The gender crisis theory may actually work because I remember Alison used to call Lucas Hermy the Hermaphrodite.
If Lucas is under that mask, then this would actually be sort of brilliant. It would also fit the anagram that someone made of Nerd Lucas is the liar. He was in Season 1, and also in Season 3.
They showed the L last in Charles in the episode, which could indicate Lucas.
I'm now leaning towards this tbh. It fits very well if you look at the evidence.
For now though, this episode was disappointing
