I also don't believe Ford's "I want to go home" speech was a lie. That was really the only time I felt like we were actually talking to Aiden. There is definitely a Jekyll and Hyde relationship between Aiden and SuperFord, Oh, and before everyone goes dooming Ford because of their capture, the Wraith know that a lot of the expedition made it to the Alpha Site, so there's no reason to think that just because they find a few Terrans running around they'll assume the city is still exists.
It would seem like the female Wraith are the one's with the most powerful telepathic abilities, so possibly if she is able to read Shep's mind, the jig is up. I'm guessing something happens to free him before she is able to do that.
Great episode! The fact that Teyla and Ronon (and Rodney) are on the drug bodes well for an eventually Ford recovery. Since we know that Teyla and Rodney (maybe Ronon) will be cured from the drug, maybe the same procedure would work for Aiden.
I'm not entirely sure Rodney is really on the drug (or maybe his artificially-imposed ATA gene is blocking its effects) because he isn't behaving at all like like the others. Well, Jace seems pretty well-adjusted so maybe if you start out a genius you don't get quite as aggressive. Too bad Jace had to die. I liked him.
