I want to call out to everyone the BRILLIANT usage of the medical transporter incoming warning during the war scenes of the episode.

I don't have PTSD, but I do have cPTSD which is close enough, and the way the sound designers utilized that medical transporter incoming warning seemed VERY clearly an attempt to demonstrate to viewers how PTSD triggers are formed.

Like--so many shows focus on explosions and stuff as a PTSD trigger. Because usually you talk about the soldiers as the vets, not the support personnel.

But with the MEDICS--that sound, going off again and again and again, when they were already overwhelmed and didn't have the staff or equipment to deal with the incoming wounded...

It's so clear to me that that sound alone, telling them they're about to get more dumped on their head when they can't even deal with the ones they already have, is meant to be fixated in the viewer's memory to sort of demonstrate how it'd get lodged as a trigger in the medic's memories.

It was just a fantastic use of sound design to help tell the story. They did it with such a deft hand that it didn't come off as poor sound design (as it could have), but was still CONSTANTLY THERE, putting everyone on edge.

I wouldn't be at all surprised if we hear that sound in a later episode and either Chapel or M'Benga (or both) completely hit the roof.

Edit: Unrelated to the sound, I also like how they had M'Benga and Chapel fix up the young man, even resorting to "medieval" medicine by manually pumping his heart--only for him to go out and then COME BACK dead.

It just gives a feeling of hopelessness. They spent so much time fixing him up--and he died anyhow after he was sent back into the meat grinder.
