Norman didn't want to believe it.
After uncovering Ray, he was a traitor and was able to not only get him to stop but also to work for their side instead of mamas, Norman thought they were finally back on track.
His little bubble was popped, though, when he noticed Mama still somehow figuring out what was happening, even Ray was very confused.
There was another spy, and Norman was ready to blame everyone, but you.
You were the reason Norman was determined to take everyone, though it was unrealistic. You were one of his best friends, crush - though he would never admit the latter.
How shocked Norman was when he found out he had nothing on the others. You were the only one slightly (very) suspicious now that Ray was out of the picture.
Norman wanted to prove himself wrong, very wrong, so he made a plan.
You fell for it, and now you were sitting on a bed, Norman, in front of you, staring at you in disbelief.
Norman was so near to just pretending you were on their side and continued acting like there was nothing wrong.
"You're a traitor too, aren't you?" Norman asked, looking at you blankly, though he was feeling a lot more than what he was showing.
The room was dead silent, the chattering of the kids downstairs being blurred.
