The plot shows how the spark of G1 Megs talks to BW Megs, explaining why BW megs was a bit 'off' in season3. Megatron even talks to himself (aka G1 Megs) so much that his own crew starts questioning his sanity (more than usual). This lost episode also features BW Megs with Quickstrike (right before his trial). So we actually get some of Quickstrike's POV on the situation. It also features, at the very end, the 'deleted scene' from BW where Optimus puts G1 Megatron's spark back BUT LIKE---in the story by Simon Furman, he says that BW Megatron, looking at G1 Megatron's face, actually sees a hint of a smile!
