Looking for an episode; can anyone help? ["Shadow-claw" passes thru Zak]

Hi Everyone!

I've been trying to find a particular episode of GA; I would say it was probably very early on in the series, but I just can't find it! But I'm betting some of our long-term fans may remember what happened in this episode.

Again, I may be wrong, but I think this episode took place before the Goldfield Hotel "flying brick" incident.

Zak was in a hall, and someone was taping behind him. On the wall, you could see a clear silhouette of Zak's stomach and/or right side. Then all of a sudden, this clear outline shadow of a monster-type looking hand seemed to pop right out of Zak's midsection. If I recall correctly, I think the guys didn't even notice it right away. This shadow of a gnarly hand with thickish fingers that seemed to come to points -- as if it had more like claw fingers rather than human fingernails -- just quickly passed through the shadow outline of Zak's stomach area, the hand seemed to pull slightly downward as it sort of looked like it was going to 'ball up into a fist' or make a brief 'grabbing motion', and then it retracted backward right back into the outline of Zak's stomach where it came from.

It was very fast; I don't think it actually took two full seconds, which may be why they didn't recognize it right away, and caught it on a later playback.

Do any of you recall which episode this happened in? So far I haven't found an episode synopsis that mentions it, nor have I found the right episode.

Thanks very much in advance if anyone can steer me in the right direction!
