Well, the phrase means in this situation that I knew you were a noob because Noel is your main. So you didn't need tell me because you main Noel, so that ratted you out.
I hope that makes more sense.
Ah.. I see. Back then, I used to main Ky. I tried Jin here, but he doesn't feel like Ky at all.
I'm trying to main Noel for a change. It's been 2 days of button mashing. >_<
