Pickups would solve a lot of problems, yes, but as most of the cast doesn't quite look like they did in 2004, even if we had the sets and people were close together, they wouldn't do much good.
Not to sound like a wise A** here, but thinking creatively, this would be workable to a "Time Trevel" episode. Just think about the cast fastforward 7 years to help solve this episode! I mean the options are all over the place!
I made the "Exeter Act 4 is not Imposible" video on youtube. Now I guess I should make a "Exeter Act 4 TIME TUNNEL" teaser.
