When you search out a new relationship or give focus to an existing relationship (not an ally or companion), roll +heart.
On a strong hit, you create a connection. Give them a role and rank. Whenever your connection aids you on a move closely associated with their role, add +1 and take +1 momentum on a hit.
On a weak hit, as above, but this connection comes with a complication or cost. Envision what they reveal or demand.
On a miss, you don't make a connection and the situation worsens. Pay the Price.
