#2. Randy Orton immolates Alexa Bliss at Fastlane
This time at Fastlane, Randy Orton could go through with what he didn't on RAW. RAW in 2020 ended with a cliffhanger as Randy Orton was seemingly about to set fire to Alexa Bliss.
Although it wasn't shown, he stopped and revealed that a moment of hesitation prevented him from doing it. A finish at Fastlane with major shock value would be Randy Orton going full circle and immolating Alexa Bliss.
It would be an appropriate way to set up The Fiend's return at Fastlane.
#1. Randy Orton destroys Alexa Bliss to set up The Fiend's return
This could be a highly-likely finish at Fastlane, and we would argue that this has the highest chance of happening. While there will likely be supernatural elements in the intergender Fastlane match, the chances of Randy Orton destroying Alexa Bliss are high.
Just like how Randy Orton destroying The Fiend set up Alexa Bliss' return, the same could happen in the situation vice-versa.
