Overview
This will help you get the whole group to find Clementine
Christa and Omid
These two are pretty easy to get. If you show them your bite, they’ll go with you no matter what. Like i said, these two are pretty easy.
Kenny
Kenny is more of a challenge. The simple way to get him is by befriending him in Episode 1 and 2. One way of doing this is by helping Duck in anyway you can, like defending him in Episode 1, feeding him in Episode 2, and putting him down in Episode 3. If he still doesn’t what to go with you, tell him that Clementine is the only family you have left, and he will join you.
(EDIT: The “Clementine is my family” option will only work if you are at least reasonable with him. If you have massively pissed him off, he will stay at the house no matter what)
Ben
Ben is also an easy one. This starts back in Episode 3. Give him a calm answer when he tells you that he caused the bandit attack. Then in Episode 4, vote to keep him or bring Clementine to Crawford and let her vote. Also in Episode 4, when you and Kenny go looking for a boat, give Ben some confidence. To do that, tell him to watch over Omid or Clementine, he will then give you a smile and walk back inside.
P.S If Kenny is going with you already, he will speak up against Ben and threatens to stay at the house.
Congratulations!
Everyone is now going to help you find that spoiled little piece of ♥♥♥♥ Clementine!
