From shared cues between this and Tunnel Vision (2012) of the story, a significant portion of Bulkhead's battle in the caldera against Hardshell takes place within the mere seconds necessary for Miko to hand a phone to Vogel, even allowing for every edit to have unknown time passing.
Agent Fowler takes a communication from Optimus Prime. He takes more time than depicted in Triangulation (2012) to respond to the call as here he had to disconnect from Bulkhead's comm.
A scene from Triage (2012) replays in the background about recovering the Iacon database, but with additional lines from Agent Fowler not depicted in the original, removing Rafael's smile to Ratchet in order to react to Fowler. This scene was also in the recap along with Ratchet's glee over reporting his success to Bulkhead, but as it plays out, he's aware of Bulkhead's condition prior to his return thanks to Agent Fowler attracting his attention, making his glee inappropriate.
