Here's a thought as I had; as of the One Shall Rise parter, Megatron had his mooks gather up a load of Dark Energon and dump it in the ship. Cool. But wait; it's never mentioned again. So, what became of the Nemesis' storage? Is the whole load of Dark stuff still there, just that everyone's forgotten about it or did it just disappear or something when Unicron got owned by Optimus?
