Stretching so his back and arms cracked in various places, most pointedly in his wrists, Leonardo huffed and quirked his mouth as he looked over the blue prints for some machine or other for Cesare and his army. Something that shot flaming arrows out faster than the most guiled archer. He scratched his temple, unsure of how to go about it. Gear system? Ropes and pulleys? A lever of a sort would help...
A smile lit up his face as he finally figured out what he was doing with this crazy thing, scrawling notes down in his mirrored text with a short stub of red charcoal. He'd been stuck on this idea for quite some time, sketching out things that made the most sense, trying to figure out how much they'd cost. It was all strenuous, and very confusing. He didn't like being caught in a fix.
So when the door opened to his new work-shop and strong arms wound around his shoulders with warm lips pressed to his neck, Leonardo jumped and lashed out, his expression angered and vehement. Well, there went his train of thought.
"Cesare! I'm working, you dolt!" he barked, scowling with pursed lips at the startled man. Cesare felt his eye twitch as he pressed his arms firmly to his side, looking away from Leonardo with a small grimace.
"Uh...I was just...going to ask you if you wished...to..." he trailed off when Leonardo's glare turned impossibly deeper, eyes glinting. He had a damn idea, and Cesare just came in and ruined it! He wanted to deck him, and made it known to the man.
"If you don't leave in the next three seconds, this charcoal is going someplace where the sun doesn't shine, get me?"
The Spaniard was out the door in record time.
