I'm putting this here NOT because it will happen, but you never know, and I know lots of people who don't read spoilers don't like to read speculation. And this is completely speculation. Did I just put a disclaimer here? Anyways, so I was rewatching Truth Takes Time (which was beyond excellent!) and writing a review of it, and I just had a lot of questions. So we all know something is up with Irena, 'cause why else would she have lured Sydney out of the building before it went kaboom? And then the secret message with the earrings morse coding truth takes time. And when Sydney shot her in the shoulder, she dropped the disk. When Sloane or Sark asked her if she had it while they were escaping, she didn't really seem too upset about the fact that she dropped it. Of course, she never was one to really show emotions, but I would have thought she would have reacted a little differently. And then I thought about Jack putting the passive transmitter on Irena after he took out the original one. How could Jack have gotten it into her without her knowledge? I'm a deep sleeper, but I'm pretty sure I'd notice if someone is planting something metal into me! Maybe Jack drugged her. But I seriously doubt it, 'cause if she was drugged, would she really have been 'in the mood,' if ya know what I mean? SO... maybe Irena and Jack are planning something of their own? I know, this is crazy stuff. But wouldn't it be interesting?
