Ben Browder shares your opinion.
I tend to agree. It's just at the right time in the series for that to have happened. He's been beaten up basically since he got on the ship. Then Crais took it to him. Then the ship is *pregnant*. And not for nothing, no one thanked him for the quick calculations that sling shot them away from Crais so they could starburst. Their little prison break would have fizzled fast.
I would also point out, that it's a good character building episode for Aeryn, who was basically all soldier soldier soldier, and was the one to crack the case that the planet was emitting the 'technology shield' or whatever it was.
And you're all missing out on the best exchange of the series.
John: I'm going to get some air.
Aeryn: There's plenty of air in here!
Zhaan [touching Aeryn's hand comfortingly, shakes her head]: He is Crighton.
I mean, gold.
