Edith was used to being alone during the apocalypse. Used to raiding and killing when things got nasty. It wasn't a nice world where you could go down the street and pick flowers anymore. It was a dead world, where friends had been infected by radiation poisoning. Your next door neighbors could be the person you shoot in a raid.

Nothing mattered anymore. Not even what gender you used if you still bled like a girl. They found that when they bled, it was harder to get away from the infected. Like their blood was a curse for attracting the dead.

So, when they found you, it was hard to change their routine. To live with another person. But it slowly worked. "4 infected up ahead. We need to move slow." Edith whispered, signaling for you both to move on. Taking cover behind the corroded cars. They could kill the infected, sure. But in the city? You never knew how many were really there.
