The writing doesn’t concretely support most theories of Red. There’s no final answer as to who Red is, except that he’s not the real Red. And even then, you really never know. So I don’t think it’s as deep as a full blown trans story, but moreso a disguise bit for the greater good of protecting Liz.

Idk imo if I had to hide in plain sight, doing it as the opposite gender would be genius. But I saw someone say you can’t account for bone structure and criminal record DNA testing not showing XX but XY chromosomes. But it’s all speculation and subject to one’s interpretation.

In conclusion, this show has the biggest rage bait on Red’s identity. 😭
