I watch these episodes sometimes 4-5 times just to catch on to all the little nuances and metaphors. Therefore I can emphatically state that the reason why Christina and Mariel's pregnancies are so "different" is because...Mariel is NOT pregnant! She has a third ovary with a lot of eggs, but she knows better and she's not letting Tom anywhere near her!...LOL...Go Mariel!

I thought this episode was way better than the all the aliens-as-puberty-metaphor episodes.

Also, the Hondurans spoke in suspiciously slow/simple (read: gringo interpretable) spanish.

The hybrid Hondurans coming out of the water was way cool. Worth that whole subplot actually.

Actually, I have to add that I rather enjoyed this episode... Why is it that I always like the episodes everyone else hates? I thought that they did a nice job tying a few things up, answering a question or two and setting things up from here on. I have to admit, I was kind of let down when Tom and Russell showed up at the Derek/Christina house and there wasn't some kind of freakish alien den with all sorts of crazy giant creatures running around or anything.. But maybe we'll get that next episode.

This is one of my favorite shows this year, but unless there is going to be a season 2, I don't see how this show can wrap up in any satisfying way this year. If it goes on to a second season, I would guess the next season would deal more with the hybrids overtly acting in the area.

Have you noticed that the Aliens always return, relatively unharmed, any impure huam they encounter. Why?

Dub Aliens can't cure a minor heart problem? Their's hope for humanity yet.

That Sherrif sure is building an "army", but for what purpose?

Agreed, Tucker!

Also, Jonathan, I agree that it almost seems like the show's peaked, but then again, that could just be this episode being a stinker. The plot with the Honurans in the jungle seemed to be a total waste of time--except for about fifteen fun seconds when Tom had to struggle with the fact that the taciturn murderers were 'like him'--anyway, it seemed pointless, until we realize it was Szura that came and picked them up. Which was pretty sweet, sure, but it totally could've been done in two minutes rather than ten.

So, while this show is usually super-consistent (which is part of it's draw) it had to labor pretty hard to advance its plotlines this week. We'll see what happens next week, but I still think this was a one-off, down-quality fluke.

My only guesses on the pregnancies is maybe with all that's going on Mariel and Tom haven't had sex since the whole thing happened. They do have three kids to deal with, keeping the town together, keeping ex-husband from telling everyone, etc. Either that or because she's older it's taking longer.

There are times when I'm thinking why do I still watch this show and it's partly because there really aren't many options at 10 pm on Wed. I thought Threshold was better than this show and that got yanked. Invasion isn't at all up to par with Lost so it's a big let down after a fresh Lost episode. I feel like they are going down a road where they can't come back from and it will jump the shark even in the first season too. But I'm a sucker, once I start a show it's very hard for me to give up and not know what happens... tv networks love me!

I was under the impression that Derek recently impregnated Christina, whereas we've been shown no evidence that Tom and Mariel have gotten freaky since the crash. I don't think these "others" are magic asexual beings, nor do they come out of the water with a bun in the oven.

I think it works just the same way it does for "normal" people, so if Tom doesn't want Mariel to pop out a crazy alien baby (he seemed apprehensive about the preggo Christina, when he said something like "it's what she's got inside her you should be afraid of") he'd better make sure he wears a jimmy hat.
