I don’t know whether Incursion is the season one finale, but it makes a good one. Who doesn’t like “impending doom”-type cliffhangers between seasons?
Colonel Young makes a fatal mistake partway through the episode, which is the root cause of everything that happens afterward. He gets chastised by O’Neill for it, but it’s really too little too late. Honestly I think it’s the kind of mistake that should cause him to lose his command. Whatever the resolution is now, it won’t possibly be as clean as the one he chose to skip.
Eli finally gets some bonding time with Chloe. They’ve had some moments before, but as of one of the last two episodes she’s still sleeping with Lieutenant Scott in their as-yet-unexplained relationship. (Seriously… can anyone tell me where their relationship was established in this series?) That is to say, Chloe gets to see Eli being the nice guy he actually is, underneath his self-deprecating jokes, because he’s forced to actually take care of her so she won’t die. (I hope that’s not too much of a spoiler.)
And of course the ship starts behaving oddly. (I’m sure Eli will be the one to figure it out and fix it, since he and Chloe end up wandering unexplored parts of the ship. He’s in the best position to do so, plot-wise.)
I’ve waffled about this series. It seems there haven’t been many mediocre episodes; I hope they figure that out before next season. A show shouldn’t waste time on poorly-written episodes.
