ENT: Hatchery, Azati Prime and Damage, streamed on Netflix.
We enter the home stretch of the third season, and the Xindi arc.
Hatchery: Everyone was able to figure out that Archer wasn't in his right mind, except for Major Hayes, which was a little frustrating and disturbing. If not for getting sprayed in the face with the bug goop, Archer would have been the first one to take a giant can of Raid to the hatchery.
Azati Prime: Enterprise takes one hell of a beating, and T'Pol is starting to lose it, leading to....
Damage: This felt so much like a nu-BSG episode, and kudos to the writers and producers for thinking outside the box. Archer steals a warp coil, and it is revealed that T'Pol has been shooting Trellium-D and is now addicted to the stuff.
This ain't your father's Star Trek.
