Sliders: Ruined multiverse part 4

 In "Fever," they land on a world with the plague running rampant. It's actually like the year 2020.  A lot like 2020. 

Multiverse impact: 

1. None of them had fully recovered from the plague. There's still a chance they were carrying. Quinn's girlfriend had to recover in a tent. Although their next slide was a world with widespread cannibalism, normal people could possibly encounter blankets or something containing the plague, and spread it to the rest of the world. Of course nobody cares if all the cannibals die.

It begs the question of what kind of microbes they already carry, and leave on other worlds. Maybe they are patient zero for some covid-like outbreak on a different world.

2. They handed several people wads of money from another world.  This would lead to counterfeiting charges, or some serious scientific investigation.

In the episode following, they stop an asteroid, but they had to help a mad scientist create an atomic bomb in order to do it. The impact is obvious: "If anyone messes with us...BOOM!"

Also there's the time travel/sliding device in the basement that Quinn tinkered with. I definitely seem to remember other sliders following them.
