When the cop car crawls by, it feels like his internal chronometer slows down. His gears and hydraulics tense without moving, he prepares to go from zero to one-twenty if he's spotted. But Barricade keeps rolling and the transformer in the yellow Camaro alt-mode lets himself relax. The 'Con hadn't picked up his signal. Thank Primus. Then suddenly there's the snarl of an engine behind him and 'Bee is burning rubber out of instinct, not needing to "look" back to know that Barricade had almost succeeded in having his bumper make acquaintance with his engine. His motor roars as the young Cybertronian rips down the streets, Barricade's Mustang alt-mode practically touching his back-fender.
Slag! Bumblebee thought I've got to lose this mech if I want to be able to get on with my mission! Stupid 'Con! This last thought was directed with pointed vehemence at the black and white alt-mode tearing up the street just behind him. Suddenly 'Bee stops, letting his momentum spin him a full 180 degrees. Barricade slammed on his own brakes, fishtailing to kill speed as the usually cagey scout unfolded into his undisguised form and faced his pursuer squarely, cannon pointed directly at Barricade's hood. "Leave me alone Decepticon!" he demanded in Cybertronian.
The morosely coloured Decepticon "chirped" his siren in surprise. Sullenly he too stood up, staring down at the surprisingly angry looking younger transformer with ruby-coloured disdain. The cannon was now leveled at his spark chamber, but he ignored that.
"Why the slag would I do that?" He snarled. The yellow transformer's battle mask swung down with an audible click. Silence reigned for a moment. The Decepticon rapidly weighed his options. He quickly evaluated that the risk of severe damage sustained was greater than the benefit he might derive from beating the slag out of the little Autobot cretin. He made a noise of disgust.
"Fine. I'm leaving this time. Don't expect to be this lucky again, Autobot bug." He growled threateningly. Only the cannon arm on the smaller robot moved as the Decepticon transformed and drove off. Finally 'Bee relaxed. He too transformed and continued on his way. As he rolled up to the gas station and "paid" electronically for some of the fuel, he thought to himself, Next time, HE won't be so lucky.
