[Western Crossover] Life Is Full of Surprises

At home, his tyrannical bureaucrat of an older brother has a control freak streak so extreme it is downright horrifying, a sweet tooth to rival anyone's, and a rapidly receding hairline. His second brother is a deduction-obsessed maniac with the temperament of a mischievous child, always causing trouble and trying to turn all of London upside down. Easedon considers himself the most normal one in the family. He has spent two comfortable years coasting at MI6 under his eldest brother, drawing a fat salary and doing next to nothing. Life couldn't be sweeter... until one day, his brother, whose hairline seemed to have receded another centimeter, shoved a bewildered-looking agent who resembled a teddy bear into his office. On the new coworker's first day, he cheerfully offered to make him a cup of coffee, nearly blowing up the entire office in the process. On the new coworker's second day, he brought in his beloved teddy bear and cut up the clothes hanging on the rack to make an outfit for it. On the new coworker's third day, he accidentally spilled water on the floor outside the door and pinned a string of MI6 personnel to the wall. On the new coworker's Nth day, the British government itself knocked on his door. "Take him out of here! As far away as possible!" So, on his first day on a mission with the new coworker... His partner blew up a rabbit warren with a missile, then took off in the car without a shred of honor! He ran away! Leaving him alone to face a warren full of red-eyed rabbits. The one leading them looked damn familiar, huh? "Long time no see, darling?"
