The Doppelganger

Welcome to my World

You scream as the box you were hiding behind shatters when the next shot is fired off.
"Stay here." Levi says, and you look at him in alarm. He's got that look the same look the other him is wearing, and though it's frightening on him it's also comforting. You think maybe you might just get through this.

He creeps around off to the right where another huge stack of boxes are impeding the other him's vision. Peeking out from around the stack, he can see his doppelganger calmly striding forward; gun out and a dangerous yet amused glint in his eye.

"Come out pet..." he yells. "If you come out now, I promise it won't hurt too much."
Based on the startled 'you fucker!' you hear, it's pretty obvious to you that both Levi's are now struggling for the gun. A moment later your eyes widen as a flash of light permeates the room and they both disappear.

They land about a foot apart from each other, both with a startled 'oof'. Getting up and circling each other warily, "Levi" takes a quick look around.
"What renaissance bullshit is this?"
Levi grins. "Welcome to my world, asshole."

Eyes widening with sudden understanding, "Levi" turns and darts down the alleyway, Levi following close behind. Putting on a burst of speed, Levi manages to tackle his other self and wrestle him to the ground. It is at this time, however that the ground begins to shake; and the screaming begins.
Titans.
One is bearing down on them now, an abnormal with several screaming children running before it.

"Fuck" Levi exclaims, watching his horrified other dash down the alley to safety. Thankful to have his ODM, he springs into action. It only takes a moment of his time to dispatch the titan, but his doppelganger is long gone. Ensuring the children safely indoors, he takes to the rooftops, searching. He sees Erwin and Hanji down below, sifting through the rubble but doesn't want to be sidetracked. Instead, he continues to scan the crowds for any sign of the asshole loose in his world.
It's no use though, and after a couple hours searching he heads exhausted back to the barracks. Maybe it's time to enlist some aide.

"Hanji!" He has just spotted her heading up the walk, and runs to catch up. She greets him with a smug expression.
"Well, well. Did the ladies finally wear you out? Always figured you had to have a naughty streak...."
Feeling uneasy, and also knowing what she's about to say; he asks anyway.
"What are you talking about?"

Her grin widens. "Two soldiers witnessed you down in the brothels these past two hours, having a grand old time. In fact, according to these two", she pauses in delight at the look of horror on Levi's face, "They said you didn't even bother getting a room, just enjoyed your ladies for the whole brothel to witness."
"Hanji..."
"Apparently, there was a lot of cheering."
"Hanji, it's not me I swear!" He exclaims, and half turns to dash for the nearest stairwell. "I mean, it is but... I, fuck this is frustrating. Look, if you see me don't believe anything he... I ...he says! He's dangerous!"
She's looking at him like he has gone crazy, and he rolls his eyes.

"Look, you of all people should be able to see the difference. Watch out for him! And have them soldiers clean the fucking stables!"
With that, he turns and heads for the underground.
