Context: Kaboom figured out that Violet was an Imposter, and he couldn't stand for that. So he knocked Violet out, and did Brain Surgery on him to remove the Imposter Parasite lodged in his brain. And Kaboom was successful! (Sorta, there's still a few tendrils of the parasite in Violet's Brain, but basically not an imposter anymore, also can't shapeshift.) Kaboom and Eclipse then locked the parasite in a tight glass jar and put it in a deadlocked cabinet in Medbay. Kaboom and Eclipse are the only ones who know about the Jar. However...it seems to be gone. And the Cabinet is broken. (During the Surgery, that was probably the most stressed Kaboom ever was, and maybe ever will be.)
