---Spoiler Alert [Known Facts/Mild Observations]---
Fact- The movie is called Revenge of the FallenObservation- In order to extract revenge, one must have been wronged. More directly, The Fallen was wronged by someone, somewhere and will get his revenge in this movie.
Fact- Wheelie finds The Fallen.Observation- This event occurs while Wheelie is a decepticon. The autobots would not seek out a harbinger of destruction for any reason, let alone try to revive it.
[Note- Though it is a Bay movie...]
Fact- The Fallen is Factionless.Observation- As there is no faction associated with The Fallen, this leaves the door open for which faction will be on the receiving end of his revenge... Or he predates the factions altogether.
Fact- Legends Class Jetfire has the same build [posture, structure] as The Fallen in both Alt and Bot modes.Observation- The film is called TF - Revenge of the Fallen... The Fallen will have it's Revenge... The Fallen looks a lot like Jetfire... TF - The Revenge of Jetfire... Jetfire will have his Revenge..? Why would Jetfire seek revenge on anybody?
Fact- In G1 [as reference only, like Bay...], Starscream and Jetfire were on the same side, there was an incident and Starscream abandoned Jetfire to his fate. Observation- This relationship to Jetfire, in addition to Starscream's character traits [conniving, traitorous], leaves a door open for a revenge scenario between them.
Fact- Wheelie and Jetfire are decepticons first, then switch sides.Wheelie switching sides after awakening The Fallen. Jetfire switching sides before/during the climax. What are the odds of 2 decepticons, independently of each other, switching to the autobots when their moment of victory is at hand? Maybe they left together, weak little guy and big strong guy?
Fact- Legends Class Jetfire combines with Legends Class OP.Observation- After turning sides, Jetfire finds the only course for victory is to combine with OP to stop some indestructible force [Devastator].
- Idea - After finding the Fallen, Wheelie befriends him. The Fallen and Wheelie develop a bond. Wheelie then shows The Fallen the true source of his pain, Starscream and his monstrosity, Devastator [think G1 Bruticus]. Starscream takes action against wheelie for belittling him to The Fallen. The Fallen learns the truth from the horse's mouth when Devastator whips his ass on Starscream's orders. Wheelie escapes to find the autobots and seeks their aid in saving his only friend, the long lost autobot [Noun], Jetfire. The Fallen is resurrected as his former autobot self, Jetfire. When Wheelie fills him in, Jetfire races to the front lines where the autobots and the humans face off against Devastator.
