AN: Takes place around DOTM in Chicago.

"You have something on your mind, Megatron? You are unusually sulking when victory is so close now."

The semi-rusted silver mech gave a dark growl, "A human insect keeps popping up in my processor. I can't seem to drown the thought of him and it's…it's driving me insane!"

The Rosenberg Panther cocked a brow at his partner, "Samuel Witwicky?"

"No, the Lieutenant Colonel of the American Army: William Lennox!" Megatron roared.

"What do you see in that human soldier?" Sentinel mused, twirling his double-edged sword as he waited for the signal that all the pillars were set.

The Decepticon Leader shook his helm tiredly but leaned himself on the cupola of the building's lower roof, peering down upon the chaos in the city streets. "There's something about him I find so kindred to me. He's strategic, brutal when angered, and he never gives in until the final option is put down. He would be a perfect liaison compared to that pompous flesh bag Soundwave watches, an ideal pet even."

It took a grave amount of control to keep the older mech from chuckling. Sentinel did, however, understand why Megatron would think that was about the soldier. When he met Lennox, he found the human rather pleasant to be around with decent humor and a military mindset even he could show consideration for.

On the subject of human pets, he wouldn't say he didn't think about taking Lennox as his own personal slave but since his associate wanted that fleshling far more than he did (and would likely kill for what he sought), he thought the second best pet he could get was the sassy, untamable Charlotte Mearing. She was the only other human he could value despite her disdainful tone. He could always teach her to respect him though.

Megatron suddenly slammed his fist into a cupola, causing the decorative material on side to crumble. It was becoming frustrating to think about the soldier. The minute he saw the man, he would probably try and take him to calm the demons this human had plagued him with. He couldn't comprehend why he was engrossed by William Lennox. All he knew now was when Earth fell and the human populace was their slaves, he would have that siren soldier in his grasp.

He gathered how the Lieutenant Colonel killed Blackout. It was technically the first human-related death any Cybertronian had heard about or cared about but it made the man a target of Decepticon interest. Although he only saw Lennox first in Egypt as he was too busy to notice him prior, seeing the human from a distance with blood stains and a gun in hand with zero tolerance for the battle made Megatron actually hesitate in perplexity. Ironically, that was the distraction that allowed the Witwicky boy to succeed in reviving Optimus despite he still managed to briefly stun him.

Ever since then, his goal had drifted from the boy to the man in a rather infatuated manner he himself didn't understand. Nevertheless he still had his Decepticons monitor Sam, but his mind was preoccupied by the soldier day and night to the point of psychosis. It was rather unhealthy to act that way but what was he to do?

"Megatron?" His acquaintance grilled.

The only words that the warlord ushered came in a harsh rumble, "I must find William Lennox."

Sentinel shook his helm with a short-term roll of the optics. "You know, this type of obsession with this human will destroy you in time. If you do acquire him, what will you do then?"

The tyrant stayed silent. What would he do once he had his pet? Study him, break him, or maybe mold him to his liking? There were many things he could do but none of it mattered at the moment as the first step was to catch Lennox first. And there was nothing he could do to get that blasted human off his processor anyway.

Megatron would just have to deal with the fixation another way until then.

AN(2): I also included the Sentinel Prime/Charlotte Mearing ship for the hell of it. But yeah, Megatron's known about him for a while and wanted him as his personal slave.
