Damn Megatron doesn't look very happy. He could giving a warning to Lennox if him or any of the humans try anything funny while they work together to bring Optimus down. I could be wrong though.
I've got a pretty strong feeling this is how the scene will go...probably. Megatron will most likely play "the conceited". He doesn't like humans so to no one's surprise he will show an aggresive attitude towards Lennox and the rest (unless Lennox's team are actuall evil in this movie and share Megatron's motives but that's highly unlikely). He will refuse to help them at first in an effort to provoke an even greater sense of desperation in them. Like he knows they need him but he can't miss the oportunity to feed his ego. So he slams the axe as in means of reluctance of working with the humans and then as the echo caused by the sound of his blade hitting the ground goes away..."So be it...human!" He agrees to form an alliance OOOOOOOOOOOR I could be entirely wrong.
Well Lennox is part of the same team as Carlos(I think that's his name in the movie) wich is the human villain in this so I guess The guys from TRF are not really good guys but I doubt they have the same motivation as Megatron either way.
