Sonic X episode 78 alternate version

Remember Sonic X? Yeah I don't either. It was an anime/cartoon that aired on the 4Kids channel on television. I have worked on a couple of episodes of it. You may have heard about the episode 79 with Sally story but that was not an episode that was ever worked on. However there was an alternate version of the final episode, So Long Sonic. The episode was about everyone teaming up and destroying the metarex. Of course i bring it up for two reasons. 1: The death of Cosmo. The one you all know and 2: The alternate version. One day I was getting off work to go home. The next day was my son's birthday and he loves Sonic so I decided to go to the manager. I asked if there were any special dvds or episodes of Sonic X. He told me to bring this home but watch it first. I took that as a yes for the birthday gift. I went home and collapsed the minute I got in the house. The next day was my son's party. He got lots and lots of Sonic related stuff. I showed him the present later that night. He got so excited that he wanted to watch it immediately. We popped the disk in and I remembered my manager said to watch it before showing it. It started off the intro in static. I noticed that Cosmo and Tails were removed in the intro however. It showed Sonic and his friends in space. Sonic was looking more depressed than ever. The Metarex was approaching Sonic and his friends. Cosmo sacraficed herself but it didn't work. Tails began saying depressing and suicidal things like why and it is my time. Tails began stabbing his eyes over and over again. I couldn't take any pictures. My son kept crying and crying. I kept watching. The metarex destroyed Sonic and the others. Blood and guts were everywhere. It cut to the credits but except they were silent. At the end it showed a face. It looked lke a bloody Cosmo. I shut off the TV and me and my son went to bed. I have removed every Sonic thing out of my house the next day.
