Actually we all knew since he came forward!
Actually you said: "As for how I know it was you? With the info I had on you previously, plus the write-up, my suspicions were directed to you. I accused you on a hunch, actually, so thanks for confirming it."
So you didn't know it was her. The information you had previously could have been learnt from the several pages before or you scumnag teammates?
You cannot prove this so you could just as likely be saying it.
I would like to know what you know about Eddie's character to see if it simply more than what she has reveal so far. I know her whole name, her description which everyone knows and everyone knows her power. So what is there that you have "learnt"?
