#3 (Positive and Negative) Luke Harper's involvement in Bray Wyatt vs. Randy Orton
This may be confusing, but Luke Harper's role in the feud between his former leader, Bray Wyatt, and Randy Orton varied over time. At first, he did great. The subtle nature of his suspicion of Orton was expertly portrayed, as the Viper successfully got Harper removed from the Wyatt Family.
Harper, now known as Mr. Brodie Lee in AEW, was getting excellent reactions as he transitioned into a babyface, stepping up to Bray Wyatt and Randy Orton time and time again. He had a bone to pick with both men. Orton, because he split Harper from Wyatt and Wyatt, because it was his delusion that caused the problem in the first place.

At one point, it even seemed like Luke Harper would go on to challenge for the WWE Championship at WrestleMania, but it never came to fruition. And once Orton turned on Wyatt, he was merely a secondary player in this feud that he was a big part of beforehand.
Despite a surge in momentum, Harper ended up in the Andre the Giant Memorial Battle Royal at 'Mania and had zero involvement in the WWE Championship match. He did show up on the SmackDown after the event to team with Randy Orton against Bray Wyatt and Erick Rowan.
This was a terrible move that lacked any real continuity. There was no reason for Luke Harper to team up with the man who separated him from his "family". His initial involvement was excellent, but things turned sour really fast as WrestleMania approached.
