Мафия 65. S1-ut system: criminal scum strikes back!

How does that work? Who and what should do?

He simply asks the GM for clarification. No action is required from anyone else; the Coordinator does not receive any information herself, but if she dies, the colonel will no longer be able to receive information. The role's status is: alive/dead.

Reven is teasing, giving such a role feature without a skill check, good job.

Actually, she initially had a skill check, but I removed it later.

Just like the guard checks, any one can be chosen?

Yes.
