Mission 21.1 -> Says the guard is 39 when he was born in 1981 and died in 2015. Don't make me feel any older than I am! I was born in 79 and ain't 39 just yet here in 2017!
Maybe he had an encounter with a temporal anomaly at some stage in his life and gained a few years...?
he wouldnt be the first one, though our latest encounter with entities causing temporal anomalies, send its victims into a later point in time, causing them to actually be younger then they should be
I'm perfectly OK with that sort of anomaly ------- Yay! I finished season 1...wait, it's what year now? ... Now I feel less smarts.
