I have an idea. Let's make a post chain. It will work like this:
1 - We will write a quote
2 - An important moment about the character,
3 - A confession of us about that character left us in above comment (We must write an another character name for the next user to write down something about). Example:
User1: John: "We are not the only people on this island and we allllll know it. ( Jack )
Lostymind: When Jack crid in the morgue, I cried too ( Claire )
Let's keep on from Claire.
