A meeting was called to the Whitehouse, Leon hadn't arrived yet. The lights had started to go out along with the power, causing confusion and worry.
Immediately, men were rushed in to protect the president. By a little further investigating, it appears that zombies had been in the Whitehouse. That's when a gunshot was heard, along with footsteps.
"Sorry I'm late." A voice called, it was Leon with a gun in his hands. Did he always carry those? Who knew. Leon was the last agent to show up.
