It was so obvious that I thought the only way they meant for it to be so in your face is if they were a red herring, there was no way they were actually gonna make it them.

But there are no red herrings when it comes to the identity of the traitor. There is only one other possibility, and even then, it requires bullshit to explain.

It sucks because until the not-twist reveal, I was super invested in the character and seeing what their actual role is in the story e.g. they were actually a good guy who's just working behind enemy lines the whole time. But...that never happened. They really were a bad guy. And just...everything I felt for them was gone.
