A small square panel is at the heart of the detonator, held in place by a screw at each corner. These are pulled out via Raven's telekinesis, and Cyborg reaches to remove the panel. Behind it is a rotating, glowing red sphere.
Cyborg: The chromium core. Very unstable. No sudden moves.
He holds up the panel; Beast Boy quickly turns into an octopus, takes it from him, and sets it aside gingerly. As Cyborg reaches toward the machinery, Starfire gets ready to sneeze, her allergy exacerbated by being this close to that much chromium, and throws everyone into a panic. Raven creates a shield around the Tamaranean's head to contain the force of the coming blast; it holds, but just barely, and her hair is blown wildly out of place. She sniffles after the shield is taken down.
Starfire: Please continue.
y/n smooths her hair back into place and she grins widely with an embarrassed little giggle. Cut to Cyborg's perspective; he holds up his forearm, which now shows a panel with a circuit diagram of the device. Three lights come on underneath it. Beast Boy resumes human form.
Cyborg: Okay. Now all we have to do is decouple the-
He uses the torch to sever one of the cables running to the core. It begins to beep and rotate very quickly.
Beast Boy: Well, that doesn't sound good.
y/n: It sound so like my alarm.
We are back in Slade's lair. Robin tumbles across the floor and stays down for a few seconds, pounding his fist against the tiles with a loud groan. Slade steps into view near him; tilt up from feet to head.
Slade: I understand your frustration, Robin. You hate losing as much as I do. One of the many qualities we have in common.
Once again, Robin's sorest spot has been poked too hard, and he comes up into an uppercut that lifts Slade clear off his feet. Two more punches send the armored criminal genius to the floor, but he lands in a crouch and runs off. Giving him no quarter, Robin lands a string of savage blows to drop him flat on his back. Close-up of the transmitter; the Boy Wonder steps into view nearby and picks it up.
Robin: It's over, Slade!
Slade: On the contrary, Robin.
The thing starts to spark.
Robin: Huh?
It breaks apart in his hand with a small crackle of electricity. He stares down in total confusion; cut to Slade, stepping out from a dark recess among the machinery.
Slade: This is only the beginning.
Robin: Where's the real trigger?
Slade: Trigger? There is no trigger, because there is no detonator.
Robin's eyes widen even more. Cut to the detonator core, still beeping and spinning like mad. Beast Boy's teeth are chattering a mile a minute as the two girls stare over Cyborg's shoulders. y/n stands ready incase Starfire's nose decides to prick.
Cyborg: Moment of truth, y'all. Everybody ready?
Beast Boy: I can't watch!
He covers his eyes, but parts his fingers to give one of them a clear field of vision. Cyborg rakes his flame across a couple of other cables to cut them, and the core stops its activity entirely. The red glow fades to leave the sphere looking like an ordinary metal ball. Beast Boy, Cyborg, y/n, and Raven sigh loudly and visibly with relief as Starfire smiles; the moment is short-lived, though, as a loud, urgent alarm goes off and elicits gasps and wide-eyed stares from all five. The core starts to spin and glow again, and red light spreads from it along the cables that have not been broken. Now the alarm slows down a bit as the red lights on the detonator's housing start to pulsate, and the topmost section retracts slightly. Beast Boy screams shrilly.
