You and Will both ‘worked’ for the FBI. Mainly, just under Jack. You were hunting down a killer, as usual. But this time, there was a lead.

It led the two of you to a warehouse. You had a confrontation with the man. He pulled his gun, so you had no choice but to shoot him. But he didn't see the other man, about to shoot Will.

You quickly moved in front of Will, an attempt to get him down, but only ended up getting shot. Will had no time to react, he quickly shot the man, until he fell to the ground.
