Season 3
Episode 56 Rajiin
The enterprise buys a formula for Trillium-D from a merchant on an alien planet.  While there an enslaved woman asks Captain Archer to save her.  So he does. He bonds with her, turns out she’s a spy for the Xindi.  Archer throws her in the brig.  The Xindi attack the ship and free her.  The Xindi use her to start working on a bioweapon.  She seems to have some regrets. But we never see her again.
How many Star Trek shows deal with someone falling for a mysterious woman or guy who’s really a bad guy?  Then antics ensue, the person betrays them, sometimes has a change of heart.  It’s a snooze fest on every level.  Skip this episode, the minor enjoyment of humans trading simple kitchen spices for an expensive metallurgic formula is entertaining but wasted on such a bland episode.
