Loved the episode, it wasnt the best, but it was still very good.
Headmaster and Meltdown have been 2 very good human villains, I'm sure the Decepticons will use them to good effect later on in the season.
Bulkhead has had plenty of character development time now, but still needs a backstory, I'm sure that he and Bumblebee will have both their backstories fleshed out in the same episode in the future.
Interestingly Bulkhead was not upgraded by the Headmaster at all, instead the Headmaster unit itself was upgraded.
Lots of funny one liners from Bulkhead, a slightly less annoying Bumblebee, Sarri using her key only when needed, use of Ratchet, Prowl and Fanzone and a good human villain makes this a great episode in my book.
Looking For: Wreckers Saga TPB Collection (with Requiem)
