One thing that stood out to me during this episode is how the camerawork was used to highlight Lucy's feeling of isolation. Particularly during the shooting in the alley and at the hospital. In these two scenes, she is seen mostly on her own, separated from everyone. And because of this, it is so easy to relate to her sense of anguish and pain.
But at the same time, the camera zooms in on the team. When Lucy is in the alley, we can see how worried Angela and Nyla are. But Lucy can't. When she goes down, we can see the look of horror and fear on their faces. But Lucy can't.
And then there's the perfect symbol of her radio being shot down. Her mean of communication with her team is broken, she has to rely on signs. And that's a perfect metaphor. So when Nyla compliments Lucy's ingenuity, we're the only ones who can hear it. Lucy can't.
And then, there's the hospital scene where we progressively see Nolan, Bailey, Aaron and Celina showing up for Lucy. But she can't see that because she is in another room, because she has to be isolated pending IA investigation. When Grey asks Wesley how she's holding up, she can't hear that. She can only see the side glances. She is not even technically alone, there's a guard there with her in the room but he can't talk to her. We don't even know if they know each other.
The way the camerawork showed the duality of this story is so important. Lucy is technically not alone and yet, you can still feel that sense of isolation. Because it looked like only Tim was there to comfort her. Making him her only lifeline at the moment. And that is going to make the next part even more heartbreaking when he disappears without telling her.
6.04 has a very subtle but hilarious nod to Something Being Very Wrong With Sam™️ when Sam tells Dean not to kill Crowley because "A deal's a deal". Sam in season 5 would have snatched the lighter out of Dean's hand and thrown it into the grave before Dean could even think to consider it lmaooo
