With a glass of milk in the hand, Shepard sat down on the couch in Anderson's apartment. The first real moment of silence since the Reapers hit Earth. "I have put my all into defeating the Reapers. While we hit them hard in the beginning, they are pushing us back without mercy now. Thessia is lost and Cerberus is wasting what little time is left by disrupting everything with the irrational fantasies of the Illusive Man. And still, I am sitting here not doing anything against it. Hackett sent us all on shore leave and Anderson left me the apartment out of the blue. Even throw a party? What's the point? The Reapers won't take a break!", Shepard thought.
Shepard's line of thoughts was interrupted as the terminal in the apartment sent a loud notification for a new e-mail. Hoping for the news to be able to take the Normandy out and start the final push against the Reapers, Shepard rushed to the terminal to check.

From: Jack
Shep!
I hear this Silversun Strip place has a combat simulator, and I felt like kicking the crap out of something. Get your ass down here if you're game.

"Jack wants to go to the combat sim? Might as well be the most useful thing I can do with my time right now.. The Normandy is still in dry dock. At least I won't forget to fight! And it seems Jack needs it as well.", Shepard quietly mumbled and sent a short "I'm game" to Jack.
After emptying the glass of milk, Shepard got ready and left the apartment to the Strip.
"Hey. Glad you could make it. I've got us set up.", Jack said once she saw Shepard.
"Anything for my crew. You carry!"
"As always", Jack replied and then both of them got ready for the fight.

In a chaotic fight, Jack and Shepard made Cerberus enemies look like fools without a break. Biotic explosions, charging and running around like headless chickens, the match had it all! The audience is thrilled and entertained while the fighting duo is racking up its score.
Since they were breezing through the first few rounds, the operators of the simulator ranked up the difficulty significantly towards the end. It made for a good show and a tough battle but Jack and Shepard did not give up.

The moment the simulation ended, Jack said "You know, if there is a god, that's what she sounds like. Just a big deep BWOMMMM to let you know everything's gonna be okay. Thanks for coming Shepard!"
"Wouldn't have missed it! And you're right, everything's gonna be okay. Let's show the Reapers they have done a big mistake attacking us. Thanks Jack, I needed this!"
