In the teaser we see an alien being hunted down by people with green lights. They hunt with flamethrowers

There’s another T’Pol/Trip neuropressure session

They look at the Xindi data they got from the last episode. All it tells them is information on one of the other Xindi species and a planet where some Xindi visited once. So they go to the planet

Reed, Hoshi and Archer start transforming into the same kind of alien we saw at the beginning

T’Pol only transforms a little because she’s magic-vulcan-immune

The main problem with the episode is how unwatchable these three weirdos become

Some other aliens show up in a couple of cool looking ships

They say that they have to kill everyone that has the virus

They need some of T’Pol’s magic immunities so Trip runs and gets a peach that she took one bite of before putting it away

Archer and Hoshi are drawn to an underground city, but when they get there, it’s not that great

Hoshi stands kind of like this throughout most of the episode

The exterminator people come after them!

The virus was meant to preserve a species that could no longer reproduce. Archer feels bad about destroying it, so instead they put the virus in a box where no one ever sees it again
