Believe it or not, this is one of the few times in wrestling history that a storyline is real. While Matt was out with his knee injury, Lita actually did cheat on him with Adam Copeland (Edge). The WWE sense a tense situation coming, so they released Hardy. Once the Lita/Edge/Kane storyline began, people started chanting "We Want Matt!", and Vince saw the dollar signs, so he re-hired Matt Hardy. I'm pretty sure that Edge and Matt and Lita have cleared up any bad blood, but the story behind the feud is very real.
