For me, this episode showed why we must allow slow-burning shows to develop before start complaining and demanding answers to questions. It is two seasons in, and this episode just reached right back and resolved a lot of unanswered questions and plot lines. We find out more about Peter and more importantly, why Walter did the things he did. We see a little more about The Observer, an interesting development on Nina Sharpe (or rather, an insight into why she is the way she is - won't say anymore than that). We also see Walter's arrogance - ("there's only room for one God in this lab ... and it's not yours") and yet we are moved by his love and compassion for his son. In my opinion, this is the best episode of the whole show - in one swift move, it tied up a lot of loose ends. In the future, I will not complain about the filler episodes which are necessary to beef the show out, as long as they keep these kind of episodes coming regularly
