Jensen opens the door carefully, positioning his body so that he is blocking the view into the room, and only opening the door as much as is strictly necessary.
He nods at the two silent men before opening the door enough to let them slip inside, taking a look up and down the corridor to make sure that it was still all clear. He wasn't overly worried inside, it was getting the body into the waiting transportation and away without arousing suspicion that was going to be more difficult.
"Everything ready?" he asks, and the shorter of the two men answers quietly to the affirmative.
"Good. See anything suspicious outside?" he questions. If this is a set up, they need to move quickly, but there's no way of knowing if Chicago's finest have already been tipped off- they could be waiting outside for them to move the body- as could anyone else.
"No, Mr. Ackles," the same man replies.
Jensen belives him- after all. They're the ones who would be arrested holding a dead body if they're wrong.
Once they've picked up the package, Jensen opens the door quietly, checking the hallway once more before gesturing for the men to follow him as he leads the way outside. Stopping at the back door, he quietly inches it open, taking a careful look around for anything out of the ordinary.
A third man stands by the back of the truck, keeping an eye out, while the driver keeps the engine running. Receiving a nod from the lookout, Jensen opens the door up and lets the men through, who quickly and efficiently stow him away in the back of the truck. They are efficient, and the package is only out in the open for a matter of seconds. A few moments after that the door is secured and the men, and the package are gone.
He looks around once more, taking in the stillness of the night, before slipping back inside and bolting the door behind him.
Now that's taken care of, he needs to go and start taking care of this mess.
