Its funny all through the DOTM Megatron didnt even say or even. acknowledged him at all during the film. Do you all think he knew he was on Earth.? if so why didnt he rendezvous with him.? Would of been a good scene if Shockwave was at the tower with megatron and Sentinel prime also the scene when he orders the ships to fire on Prime he should of shouted Shockwave i need help or Megatron.?
