Rodney feels replaced

[wrinkled-fabric.livejournal.com]

So I loved 'Replaced' by thought reflex and wondered if there was anything out there similar, where Rodney feels very insecure, and thinks he's only wanted for his brain and no one actually cares about him personally.

I love team fics so hard and Rodney and John's friendship, I'm not big into slash so would prefer Gen.

The longer the better and if I read something that doesn't end happy I'll be sad all day, so happy endings only please :)
