The Beth/Lisa parallels struck me as incredibly obvious, and even a line or two would have been enough to address it. After the episode aired, I actually wondered if maybe, in a sudden fit of continuity, Ianto's black humor was related to discomfort about the similarities. And, as you say, to his questioning whether or not it was appropriate to use the mind probe. Unfortunately, it just came across as Ianto acting kind of strange.

Sleeper could have been a big turning point for Ianto, actually. At the end, he was one of the four firing at Beth, with Gwen protesting. It's quite the role reversal from what we saw Cyberwoman. I wish that hadn't been ignored. Gwen can lecture the others all she wants about being human, but she's been on the other side too.

Full of weird and yet we love it anyway. Ah, Torchwood.
