First of all, everyone can relax. We've got a new Harrison, folks! A new kid. So farewell "blank stares of twins Evan and Luke" and hello Jadon Wells. Not that Harrison ever had to do much more than say a few words per season, but it's clear, from the opening "Wonderful World" scene here in the Season 8 premiere, they needed a kid who could do a bit more. Not much, but something. He had to fly a kite and look like he was playing soccer and such. So, a bit more animated. And if this break in continuity bugs you, you need to re-examine certain aspects of your maturation. I, for one, welcomed it with arms outstretched.
