I constantly think about the riddle Ed told Sofia in s4:e15
"I can be done with the teeth,the eyes or the mind. What am I? I can be humorous, but I'm never funny! What am i?"
I'm fairly certain the answer is narrow. It's interesting to think about considering that the show states it as him deciding not to betray oswald, but what if Sofia solved the riddle? And can it be considered betrayal due to riddles are a form of communication for him?
Or that I can just say never mind and join him in his insanity and that instead of scalping me or something he’ll have me as his little sidekick and we’ll fall in love and live happily ever after together
