@CosmicDebris:
I don't think they flat out said Brock won't be in it much. They keep saying wait and see. I'm glad they're moving the plot forward and changing people's situations. Hope Hank and Dean will survive, lol. Of course, you have to wonder, can't he just make more clones? He made a clone of that one kid that got ripped apart by a gorilla in Rusty's kid camp episode. :blink:
The entire current batch of Hank and Dean clones were unleashed to do battle at the end of season 3, and were very, VERY easily killed. Its a large part of what caused Brock to quit, in fact.
And before that they were killed en-masse in season 2 to provide zombie military fodder. (it was the scooby doo episode.)
Basically, they keep killing off all the ready to go copies. I assume they do that so theres some actual danger and threat to the situations the kids end up in. Get them away from their mind reading tech for a while, get rid of the extras, like that.
