I also noticed that this is the first episode where Agent William Fowler's given name is revealed. Could it be a reference to G1's William Irving "Sparkplug" Witwicky (father of Spike and Buster Witwicky)??
...probably not. d: So many Williams in Transformers. Sparkplug, Bomber Bill, Wild Bill, Bill Gordon, Billy Husky, Billy (from Transformers Armada), Chairman of the Joint Chiefs Bill (Keepers Trilogy), William Lennox, William Hayes, Billy North... and now William Fowler. Man, WIlliam's gotta be the most common given name used in humans in Transformers. Heck, there was even one Transformer whose name was Billy!
And yet there's only ONE character in Transformers with the world's most common given name -- Mohammed. And he's damn obscure!

Also love this quote:
"You're a motorcycle, Arcee... shouldn't you know how to build a motorcycle engine?"
"You're a human, Jack... can you build me a small intestine?"
I just love cultural faux pas moments like this which remind us that Transformers are not only alien to humans, but that humans are alien to robots.
