Alright, bear with me here. I know you're all absolutely tired of speculation threads, but I just needed to get this out there. In Triage, we're shown Bulkhead flying though the bridge with his back smoking, hinting at serious damage. From the commercial, the fight between Bulkhead and the Insecticon was very quickly shown, which led me to believe there may not have been much of a fight at all. Now, what if, unlike the other episodes, this one wasn't just focused on getting the relic? A third of the episode could be related to Bulkhead recieving medical care so he's not sitting on the floor of the base, back smoking, for the entirety of the midseason break. I mean, the title "Toxicity" has got to mean something, and that nasty-looking pocket of...stuff in the Insecticon's chest in the promo image might get transferred to Bulkhead.
