I'm reminded of the Soulmate background listed on pages 72-73 of the Judge Hunter Creedbook.<br/><br/>Basically, once per session, you can add your dots in Soulmate as extra dice to a single action that directly affects the well-being of your beloved, but there's penalties if you fail to protect them.<br/><br/>I could easily see something like that being changed from true love to the sort of connection that those two have, if Sabriel likes the idea.<br/><br/>Mage has the Twin Souls merit, but the powers just don't match up even halfway decent enough to really suggest that.
