These are also from last Septemberish. I like this picture more than the one for Runner 5's Name, but the story a lot less, overall.
I have a headcanon that Runner 5 has PTSD from the helicopter crash they came into town on. While there are others, the strongest trigger is definitely explosions. . . which makes the ends of Season 1 and so far most of season 2 VERY STRESSFUL for them :/ :/
Again, if you haven't heard of Zombies, Run! before now and you have a smartphone, my understanding is they literally JUST made it sort of free-to-play when they released Season 4, and it is definitely worth a look.
