Even though they are twins, Rohan always proclaims seniority over Ryan because he "came out" 7 minutes before Ryan. Of course Ryan completely resents this fact.....cos that makes him the youngest in the family.
They both recently got pet betta fish and Rohan was noting down his fish's birthday on his Itouch, and he then realised that his and Ryan's fish were twins!! And then immediately he said, "Wait, which one came out of the store first?"
