[Update: The Walking Dead]
[It takes days to find the way out.
Mary Jane and Peter get there first, after being spotted and chased by the farmhouse survivors who are unwilling to let them escape. It's brutal, and their battle leads them far astray from the rendezvous point. Eventually, they find a city and, with the remaining survivors still in desperate pursuit, they make it out.
Harry, Flash and Gwen take longer. They linger at the rendezvous point, unwilling to give up hope, and their supplies run out a few days in. By the time they find the door in a nearby town, they're dangerously dehydrated, starved, weak, and barely able to avoid the zombies that they can no longer shoot due to lack of ammunition.]
