Well, you could write a fanfiction where the OC has a special ability that catches Roan's attention. For example, the OC might be able to communicate with animals in the post - apocalyptic world.

In a 'the 100 roan oc fanfiction', you might consider a plot where the OC is from a group that has been at odds with Azgeda.

The story could also explore the cultural differences between the OC's group and Azgeda, and how Roan and the OC bridge those gaps.
Clarke could be a great addition. Her leadership skills and moral compass would contrast with Roan's more survival - of - the - fittest approach. Octavia is also a good choice.
