Did I just witness the Autobots use a WMD? Seriously, intense shit right there, since when has Optimus been ok with sucking the sparks out of Cons?! Freaking love that it happened though, shows a definite progression of character for Optimus in my humble nutty opinion. He's gone from the leader who's always believed that the Cons can be subdued without too much violence, to a point where he is now willing, perhaps reluctantly, but still willing, to use a WMD on the Decepticons in order to gain an advantage...I don't ever remember seeing anything like this in close to 25 years of Transformers! Add in the fact that, at the end, when Megatron had the kids and Prime asked the question...'What if we don't (give you the keys)?' It's like he was seriously weighing up the morality of killing three children in order to save the Cybertronian race. I reckon at the start of the season he wouldn't have even considered it, but now...well, war changes people and bots alike, doesn't it? Episode was awesome, great to see ruthless Autobot action. Psyched for the finale.
