The First Strike (Zugzwang Redeux)

"JJ puts her hand up to his through the window, lets out a deep breath, and holds up the side of the note that says "ZUGZWANG". As she pulls her hand away from the window, there is a light white residue of powder from her fingers." This is a Replicator rewrite. What I think could have happened at the end of Season 8. Multi Chap, M for language, some violence.
