“The Seer” is episode eighteen of season five of Sliders and the season and series finale.
In the previous episode, “Eye of the Storm”, Dr Geiger gave Diana a disc that she said had the coordinates to get home on it. Mallory is asking Diana what she plans to do when Maggie joins them with a giraffe sandwich and a pork soda. The last chance to try the unusual. Diana asks Maggie if she’s going to stay with Rembrandt. Yes, for as long as he needs. Rembrandt joins them, having been to church. He thought he would be coming back with a way of defeating the Kromaggs, but he’s returning empty handed. Maggie says he has her. Rembrandt warns that his world is still occupied by Kromaggs, and he won’t blame anyone if they want to bail. They don’t.
They head through the wormhole and enter inside a building. Leaving it to see a crowd gathered to welcome them, including TV cameras. They wonder if the Kromaggs have been defeated, and why everyone is like this. A woman introduces herself as Claire LeBeau, and her father, Marc, better known as the Seer.
Heading inside, where there are tons of things related to them, they’re told that no-one ever expected to see them in real life. Rembrandt says it’s as if the world known everything about them, yet Mallory and Diana have never been to Rembrandt’s world. They still haven’t; this isn’t Rembrandt’s Earth. Their slide wasn’t hijacked either, but LeBeau did know they were coming.
He says that he’s been observing their exploits for some time. Some years ago, he suffered a massive heart attack and wasn’t expected to survive. He did recover, but developed a strange new ability, visions of the Sliders. He realised they were not hallucinations, but actual events, and began to share what he saw. It became popular and when the Kromaggs came, the Sliders’ exploits inspired many to fight them. The Kromaggs were defeated with a synthetic virus. LeBeau also gets occasional glimpses of the future. And the next time they slide, they will instantly die when they exit the wormhole. He doesn’t know why. He foresaw the death of their friends, and has never been long.
In a hotel room, they watch a cheesy TV show called The Sliders. Rembrandt is worried LeBeau might be right and wants to be the only one to take the risk. The others refuse. They head to a reception, and meet Maggie and Rembrandt’s doubled; Maggie reduces hers, an actor on The Sliders, to tears by saying that if the Sliders stay, she’ll be out of a job. The Sliders tell Claire they are going to slide out. They’re willing to take the risk. Then a woman comes in. Quinn’s mother, not a duplicate. The Kromaggs brought people from other Earths. Mrs Mallory is taken away. Claire, when asked about the virus, says there isn’t any. It has a short shelf life and will be assembled when needed. This will take two days. And the Sliders’ window opens before then.
Claire introduces her father, who says the Sliders have chosen to stay. They will help lay the foundations of Slideology, the ideological discipline for the future. He asks them to say a few words. Rembrandt says thank you and goodnight, as they leave.
Back in their room, Mrs Mallory arrives. She asks Mallory if there’s anything of her son in him. He bluntly tells her no. Maggie wants to talk to her alone.
If the Sliders leave, they may well die. But it seems that the LeBeaus really want, perhaps need, them to stay.
There’s a sequel hook at the end, but the series wasn’t renewed for another season, which means there are unsolved threads at the end.
