Headcanon that after they’ve hit puberty, Jon can get Damian to do literally anything by calling him “Darlin’” in his farmboy Kansas accent.
Jon: Would ya be a darlin’ and put a tracker on that guy for us?
Dami: *blushes and vocally refuses while doing just that*
Jon: *hears Damian’s heartbeat speed up but is completely oblivious to the reason why*
