I also did notice, but didn't mention, how the guy that Andor killed, betrayed one of guys, he said "cover me" and he actually didn't, shot once and stopped. He was trying to do his thing for a while. Nice bit that the show did.
And i think its a bit unrealistic how the doctor was not able to save the kid, seems like at that time technology can doa lot of shit, maybe he didn't had all the materials, but anyway.
