"Things were dictated by the times, by it being post-9/11, but I wanted us to hopefully get back to having a little bit more fun on the show and to get out of that whole Xindi thing. That would have been fun. I think we were pointing in that direction. I think the group was ready to go. The cast was ready to get there, and I think we could have had a blast. But we just didn’t get to go there. And I wanted Archer to kind of grow up and lighten up a little bit."
