Jericho wasn't advertised but everyone saw him at the Rumble and it was blowing up on twitter. So, you could just assume he would be on Raw the next night. I am not saying that Rock didn't bring in the ratings but the WWE did spoil the Lesnar thing on twitter before he came out. I tuned in because I assumed Trips would be on the show too.
