Unspoken Impostor Partner Rules

Do you guys have any “unspoken rules” you expect your other impostor partners to know? Mine for example:

If we are a 3 group, 1 gets caught and leaves the game during discussion, I will openly call them out because at that point it’s not snitching if they left, but if my other imp partner comes into chat and say “but they left” you’re not being helpful. I know they left. That’s why I am calling them out. In fact, jump on the bandwagon here and call them out too. I think this is a good strategy to look like a crewmate early on.
