I was wondering, after one episode, why wasn't Timantha brought back after so many seasons? After all, the episode The Boy Who Would Be Queen is a favorite among many fans. I would think many fans would love to see Timmy become Timantha again in a future episode. Perhaps it can be combined with Chloe becoming a boy as well.
Could it have anything do to with potential transphobia concerns? The Boy Who Would Be Queen didn't cause much controversy at the time it first aired, but perhaps in today's more divisive political age, I wonder if there would be any controversy with Timmy becoming female again.
