Ep.9. One of the Chosen double checks that each member of the chain gang is securely shackled before they are ordered to move out. Today they are heading for the farm. Alice leads the way. They are, in order:
  Alice
Ellie
Tai-San
Ryan
KC
As they leave the Mall a new kid has apparently joined them, secured to the same chain and in the lead. Suddenly he drops to his knees clearly unwell. Against orders not to interfere, Tai-San helps him back to his feet. First to last they are now:
  Sick kid
Tai-San
KC
Alice
Ellie
Ryan
That's a really neat trick, changing places with each other whilst still shackled.
When they get to the farm we see that Cloe is also included in the work party. So how did she get there? When they get back the order is Ellie, Tai-San, Alice, KC, Ryan. Seems they forgot Cloe again.
