Grommet was in his lab.
Broadwing is stopped by a guard. Unfortunately, his earlier expressing of his intent to kill Shockwave should he cross paths with him made the guards hesitant to allow the two to come into contact.
"I don't like the guy much myself, either," the guard says. But I got my orders, man. Sorry."
"Stasis pods, not cryo-tubes," Sprocket corrects him as he works at the console, "And no; the pods are fixed to the walls, it looks like."
Sprocket reads the statistics of the pods in the damaged hall. A few of them were still active, including some insecticons.
"Right," Forcep agrees. "But there's also a chance the newcomers would be welcomed and successfully integrated."
It seemed that both options- leaving behind some of Salvation's insecticons, or splitting the sparks of a few volunteers to take to the mutant hive- carried some degree of risk.
