What was the episode when the XGB defeated this ghost that possessed everyone and released bad verisons of themselves and Edurado called a elderly woman an old biddy. What was that episode? At the end they broke the mirror.
Sounds like The Ghostmakers.
From Spook Central:
oh okay then. Thanks Kingpin.
You can watch The Ghostmakers here: http://www.gbfans.com/extreme-ghostbusters/the-ghostmakers/
I think it’s really dangerous to shot the mirror with proton guns…Can you guys remember what happened in **“Till Death Do We Start” **?when Eduardo trying to do the same thing? 
That always bothered me. A proton beam should melt the mirror, not bounce of of it like a ray of light.
yeah, that’s the point. But I don’t suppose a proton beam would follow the track like that, anyhow , it’s not the laser , while the mirror could reflect most of the laser as well as it’s energy.
Yea. Definitely sounds like “The Ghostmakers”
