[ENT] Season 3, Episode 15: Harbinger
This episode has three plots going on. Two of them seem a lot like poorly executed high-school conflicts, but the third is really interesting. It also develops the ongoing explanation of the expanse, so it needs to be watched despite the 2 rating.

Notes:

At first it seems like Reed and Hayes are at each other’s throats, but they start each sentence by saying “with all due respect,” so I guess they’re cool.

They come across a big gross ball of something in space. There’s a pod stuck near the edge with a life-sign!

T’Pol is jealous ’cause Trip is partnered with that Maco skank during his sixth period neuro-pressure class.

The guy’s ship is made out of the same stuff that the spheres are made out of. Archer wants answers but the guy is too busy dying.
