He almost gets hit by a car, as Senator Morra tells him, "We almost lost you there, Brian." His condition gets worse and we see Rebecca asking Brian, "Are you okay? Are you sick?"

Then we hear Morra telling Brian, "This is about you, about whether you are just an employee or a partner. You have only seen the ugly side of what we do, there is so much more."

The scene changes to Brian telling the senator's associate, Mike, "I need that shot." However, Mike tries to negotiate and asks him to betray agent Harris (Rebecca), but Brian refuses.

Mike says, "You feel some loyalty to this woman, but when it feels like your brain is on fire, you will do anything for that shot." The video ends with Brian showing up at Rebecca's door, asking to be let in. Will he betray Rebecca for the shot?
