(S02E16) "Somewhere, Peter will grow up, somewhere he will lead a proper life, somewhere he will be happy, but just not here. And we must take comfort in this. We must begin to move on." - Walter to Elizabeth, watching alt-Peter through the window to the other universe

I've said it before and I'll say it again: John Noble is a fantastic actor. With the flashback to 1985 in this episode, he completely morphed into a different Walter Bishop. And yet, you can see traces of the person that he is now, and because of all he's been through, you can understand how he got from there to here.

But he wasn't the monster that I thought he might be, based on some of the things we've learned about him since 'Fringe' began. Instead, he was a loving and caring husband and father who was obsessed with finding a cure for his son.

This episode has gotten a lot of hype, and it didn't disappoint. While it did answer a few questions, it posed even more questions, which will make the rest of the season exceedingly entertaining and possibly heartbreaking.
