We're bringing back Sliders without a reboot.

It was the real Arturo that got left behind in "Post Traumatic Slide Syndrome", and Remy ends up finding him again after his cliffhanger solo slide.

Working with Arturo, they manage to get a slidegate up and running to go back for the others. They also find a dying copy of Quinn along the way who has some valuable Kromagg info and end up merging him into Mallory like the accident that melded our Quinn into him, in a last-ditch effort to save him. The presence of this third Quinn, who is almost like the original, outweighs Mallory so we have Jerry O'Connell back in the cast.

The gang all back together, they go to deliver the Kromagg bio-weapon in Remy's blood and succeed. It's now slowly spreading across all worlds. But the Kromagg big bad they're fighting during this process sets off some kind of nuke inside a slide-tunnel, destabilizing the entire thing and basically scrambling sliding across all worlds. Even if you knew how to precisely connect to a world before, it goes somewhere else now.

And now we're back to the classic formula, we can do whatever we want from here.
