If Sentinel was supposed to meet Megatron on the moon with the pillars, why would the cons be chasing it and shooting it? To maintain the ruse, right? But wait, they actually damaged it, causing it to crash on the moon instead, killing everyone but Sentinel, and even then seriously messig him up, hindering their plans. So either some Decepticons didn't get the memo, or there is a plot hole in the movie right there. Or I missed something.
