I often tape over each day with the next one, but I put Friday's after Thursday's, so I decided to go back over both of them Saturday night to look for some of the details mentioned in posts here and for the Thayer David credits blooper.
It turned out that it WAS at the end of Thursday and BEFORE the squeezing of the picture!! If you still have that episode you can check it out. It's right after the seance to contact Trask, when the bricks first start to break down. The credits start to roll, Thayer walks in, stops and looks, turns around and disappears back where he came from!
