Do Two Truths and a Lie for each of your (main) characters.
For those of you who don’t know, Two Truths and a Lie is an icebreaking game where each person comes up with two true facts and one lie about themselves, and everyone has to guess which is the lie.
This is not just an exercise in coming up with two truths and a lie for each of your characters. It’s an exercise in figuring out how each characters would play. Would they use it as an icebreaker to teach people about them, or would they play to trick everyone and not have anyone guess the lie? Would it be a way to brag about who they know or what they’ve done, or would it be uncomfortable because they feel like they haven’t done anything, or because they feel like they’ve done too much and don’t want to brag? Would they play strategically? Would they have trouble coming up with two interesting facts about themselves? Would they lie for all of them?
If you want to take it a step further, write a scene where all of your characters were playing this with each other, and figure out what each person would guess.
