A/N: I have not watched the episode Autoboot Camp episode yet. I conceived of this story just from the following at /boards/member.php?u41765 :

# 25 Autoboot Camp - On the trail of an escaped Autobot traitor, Bumblebee flashes back to a previous encounter with the traitor when he first met Bulkhead in Autobot Boot Camp.

- Interesting one will be #25 - BB on the trail of an Autobot Traitor... Wouldn't it be cool to have him be Doubledealer?

BB Shockwave TFW2005

Yes, BB Shockwave, that would indeed be cool. This, combined with my passion for Sunstreaker/Sideswipe and the desire to see them in TF Animated, led to this story. Enjoy.

A distant thud…

Optimus Prime did a full 180 in response, weapon ready but not drawn, as he scanned the dark area where the sound had come from. Although this assignment did not actually entail any danger, it was good practice. He congratulated himself on a perfectly executed maneuver.

A flash of yellow…

He spun back around, weapon drawn, even though…there wasn't anything here. Who would mess with a carbon mine anyway? No sane transformer would dare interfere with an energy source that supplied four major settlements. And they were all sane now…Decepticons had been wiped out before he'd even been sparked.

He cautiously looked inside the mine entrance. There was no sign of disturbance, and no sign of yellow.

He put his weapon away. Perhaps his optics were playing tricks on him, it was known to happen, especially to over-eager recruits on their first guard duty assignment trying to prove themselves to the Elite Guards even through something as simple as monitoring the off-cycle activities at a carbon mine.

But this didn't feel right. What he had originally chalked up to first-time guard duty jitters now felt more like alert autobot instincts. A more mature transformer would know the difference. He definitely saw yellow behind him, just for a nanoclick, but it was there.

Astro-seconds passed, and he began to relax.

His sensors detected a rise in heat a split second before a blast within the mine knocked him to the ground and partially covered him in disintegrated steel. Just as his head emerged from the rubble he saw…

A flash of yellow.

TBC…
