Actually, we like to think that we tied the three movies together, although the first is only barely hinted at in dialogue
(We also used the concepts from the Movie Prequel comics, especially "Foundation" by John Barber and "Defiance" by Chris Mowry).
This story was written because the lineartist Lau asked for a way to redeem DotM Sentinel Prime, who was anything but a Prime in his behavior.
And I hope this will spark some interest for "our" Sentinel Prime, the one of the Seeds Of Deception series! (Shameless self-promotion, sorry)
