Andy and Quynh were the only two immortals in existence until they started dreaming of two men on opposite sides of the same war

Once they meet, there are obvious hurdles to overcome like language barriers but Andy and Quynh can see the two men are slowly coming around to being together and starting to love each other

-Andy is often translating between the two so they can talk and she translates the more raunchy flirting with the straightest face ever

-Quynh sends them off to scout together and teases them mercilessly (like she straight up asks Joe if he thinks Nicky is a vision of God and all that and she laughs at his blushing)

-Andy forces Nicky and Joe to share a tent after slashing one of the four tents and Quynh and her sneak over to spy on them and overhear them trying to teach each other Italian and Arabic respectively

-Overtime they notice that Nicky is always quicker to see to Joe's wounds after a battle despite being immortal and Quynh persuades Joe to draw all their portraits but they find his sketchbook is almost full of drawings of solely Nicky
