Anybody with common sense of how Jericho works would know that Jericho has returned as a heel.
The thing I love about Jericho is he knows exactly how everybody is going to react to certain situations, my point being he knew he would be cheered on his return. So, being the intelligent guy he is, Jericho milked the reaction for all it's worth, held the microphone the entire time to entice everybody into thinking he had something to say, only to drop the microphone and continue being overenthusiastic. I sat there waiting for him to talk, and he didn't, and even though I was disappointed I knew what he was doing. It's so obvious.
Everything he did with that return was perfect, and that WWE.com exclusive just adds to the whole thing. I can't wait to see where this leads, although I think it could be alot more simple than everybody thinks. As usual we're all looking into this too deeply, and I think when Jericho reveals why he has said nothing, that will be the catalyst to revealing he's officially back as a heel. He has your average fan thinking he's back as Y2J and here to have some fun, which is exactly what he wants them to think.
