The Invasion (professional wrestling)
There were several inter-promotional matches after Unforgiven. Furthermore, a crucial plot point formed when, on the October 8 airing of RAW, Jericho and The Rock teamed up against Shane McMahon and Rob Van Dam. Jericho's face was drenched in blood and, with a steel chair in his hand, accidentally nailed The Rock when he was trying to hit Shane McMahon. This caused a stir backstage later on in the night when The Rock checked to make sure Jericho, who was being treated by EMTs, was in good condition but stated that Jericho made a big mistake in the match. Jericho, irritated, countered that everyone makes mistakes, including The Rock. The Rock responded that everyone should own up to their mistakes but was more concerned with Jericho's condition. As he went to leave the room, Jericho made a comment to the EMT wondering "what the hell" The Rock wanted for him. The Rock overheard this, walked back, and asked Jericho to repeat himself. Jericho did just that, and The Rock countered that his mistake actually cost them the match. Jericho countered that he maybe should have hit The Rock instead with a chair on purpose and proceeded to taunt The Rock by stating that he should knock the People's Eyebrow off of The Rock's face. The Rock provoked Jericho to do just that, and a brawl ensued.
