US - Russian safe conduct. US pilots and flying crews who flew over Eastern Europe and USSR (like pilots delivering some lend lease planes) were issued this kind of papers to avoid being captured, beaten and shot like many Luftwaffe pilots.
I LOVE your takedown on Rhaeger and Lyanna's 'relationship'. The more I see/read about him, the more he reminds me of Joffrey. He starts out handsome and charming, but then we get to see the entitlement and manipulation (his actions leads to the Death of a Lord Paramount and his eldest son, he humiliates his intended and then sets her aside, doesn't give one single shit for the consequences of his actions). The only consolation is that they both died choking and clutching their chests.
