Which Gecko brother is older?
The first time I watched this series I was under the assumption that Seth was the older brother, probably because of the way Seth acts toward Richie along with the fact that D.J. is older than Zane in real life.
But I'm on my second time through now, and I noticed in one of the first couple episodes Freddie mentions that Richie is the older of the two, which was a surprise to me. Also in an early episode a police report on the radio mentions that both brothers are "in their late 20's."
FDTD wikia says that Seth is older, and mentions that the two are only a year apart.
Long story short, does anyone know which brother is actually meant to be older? Or how old they're supposed to be?
