I did some research on Sentinel and Optimus Prime. I know, Michael Bay sometimes uses some plots and ideas from the G1 series and other series's. I did some research and it said Sentinel Prime dies in a battle and gives the Matrix of Leadership to Optimus. The Matrix was in the second one, so it's not gonna be here. Now I only have two questions.
1. Does the Matrix of Leadership come back, because there was no proof that it got destroyed when Optimus shot it, it could of just flew out and survived.
2. Does Sentinel actually die? Some pictures I found of the comics show him dying in Optimus's arms. I hope he doesn't die.
