Interesting Uses for Icon Relationships

In the 13th Age Google+ community, Facebook group, and Slack channel, I've come across several discussions describing interesting uses for Icon relationships.  Do you use Icon relationships in a way other than what's described in the core book or the GM's Resource Book?  Do you have a unique twist on how you handle or define Icons?  If so, why not share your ideas with the community?

The integration of Icons and Icon relationships, advantages, and complications into a 13th Age game is often considered one of the more challenging parts of GMing the game.  If you can shed a new light on how to use Icons or have advice to pass along to those who are still struggling with the concept, we'd love hear it.  As always, please email us at escalationfanzine(at)gmail.com.
