I agree with all of your Season 1 choices. May I also suggest DNA Mad Scientist? That was the episode that got me completely hooked on the show. You got to see under the tough exterior how emotionally fragile and scared Aeryn could be. Her talking about being "left behind" breaks my heart everytime. You also get to see the relationship between J/A (though expected) really begin to bloom in the way he races to save her while the others are consumed by their desires to get home. And what about the others decision to take Pilot's arm against his will? Wow. That shocked me at the time, but that was the point - to see how less then heroic are heros could be. Not a lot of shows would take a risk like that.

As for TalynJohn episodes, can't recall the name just now, but the one where he and Aeryn can't keep their hands off each other? Sexy and cracks me up everytime, especially Crais reactions to it all.
