I love the foreshadowing in S01E01 of The Pitt.
The first full interaction we see between Robby and Whitaker is this moment of unspoken teamwork when Javadi faints and they basically communicate around her as if they already understand each other.
And on the other side of the coin, we see Langdon, the golden boy, already not living up to that (not that we know he's the golden boy yet), he's rude and doesn't care when they have a moment of silence for the elderly woman who has passed away en route to the ER. Not particularly befitting of the doctor being primed by the chief.
I just think it's neat how in that we can already see that Langdon will fall into disgrace and Whitaker will easily take his place, at least in Robby's eyes.
And the follow through into S02 -- Whitaker has taken on so many of these behaviours, he passes on the same seeds of knowledge he was given -- he fits in that space that Langdon left better for Robby, and maybe even in the ER. His attitude is a more appropriate fit.
Man I love this show. I need that canon HuckleRobby kiss though, I'M BEGGING YOU, WRITERS, PLEASE (you know what you've put in the seeds, we can all see it)!
