Pretender Rollout

Who's Rollout, I hear most of you asking.

But Rollout never was a Pretender, I hear those of you complaining who know Rollout. True, I say, officially he never was a Pretender. In my story The Whole Last Quest, an extension of The last Quest, he was. With a Decepticon shell, even; courtesy of Piston. After all, what better use of a Pretender shell than to infiltrate the enemy's HQ in one of the enemy's own shells? Rollout's a spy, after all (who transforms/used to transform into a front payloader, mind, but a spy nontheless). Seriously, why did no one come up with this so far?
