Now that we're firmly into the second half -- and heading towards the end -- of season two of 'Fringe,' let's talk about what's happened so far, and what we think might happen. Some of these speculations will mirror those I made last September, because not all of those questions have been answered yet. In fact, we may have more questions now than we did back then.

Still, with the episode titled 'Peter,' we finally started to get into the nitty-gritty about Walter stealing Peter from the alternate universe. Of course, we all knew this, but when will Peter find out, and who will tell him? That and lots of other questions spring to mind.

Will Peter learn the truth about his origins? Yes, I believe so, but the question is who will be the one to tell him? In last week's episode, 'Olivia. In the Lab. With a Revolver,' Olivia was determined to tell Peter the truth, but then decided against it after realizing that their family unit (Peter, Walter and Olivia) was more important than Peter knowing the truth. Then Walter decided that HE should be the one to tell Peter, painful as it might be. Walter knows there's a good chance that he could lose his son ... again. One other question is this: Walter visited Peter's grave in season one. If that grave is in this universe, why on earth would they use his real name on the gravestone? What if Peter stumbled across it?

(S02E17) "I have to tell him. I've gotta tell Peter the truth." - Olivia to Walter

I wish I could figure out how Sam, the bowling alley guy, fits into everything. I don't trust Nina Sharp one bit and neither does Olivia, so why should she think that Nina's suggestion to talk to Sam is a good thing? He could be totally nefarious (even though I don't get that vibe from him).

His midnight game of Clue did give us the great title for this episode, though, so there's that (along with the fact that we got to see Finn Garrity from 'Damages' again). But even so, he's not being very helpful at this point. Is he from the other universe? "I'm older than I look," he told Olivia. "I barely remember my childhood. I'm also taller than I appear."
