This week’s episode we saw a lot of developments in Walter’s personality. He has taken important steps in going out more, out of the shell he kept himself in for some time now. This has been triggered by the return of his son. The changes are very visible and noticeable, at first; he couldn’t even get out of his laboratory, not even to sleep, as he slept in it for some time, so to see him develop like that is very nice to see. It is amazing seeing him getting his life back together.

Despite the fact that Walter went to the other side, but the events was interesting and exciting to watch. It really lived up to everyone’s expectations, the one thing that we all wanted to happen but didn’t, is for the two Walters to have a face to face confrontation, sadly, that didn’t happen. But that doesn’t mean that they will not face each other eventually, as they will have to meet sooner or later.

The cases that were presented to us on this week’s episode were kind of irrelevant, not to the grand scheme of things and the series, but to the episode itself. We got to know more about the things that has been keeping us confused for some time now. For example, on this episode we got to know more about the final plan of David Robert Jones’ and his end game. His plan is to destroy and collapse the two worlds, although we know his intentions, but we have no clue about the reasons behind it, why would anyone want to collapse the two worlds, but seems Walter is giving us some hints.

We saw Jones paying a visit to Alt-Broyles’ home, although Alt-Broyles is not one of the shape shifters, but he was being held against his will by Jones in order to give his son some much needed experimental medication because his son was dying. We could easily relate between what Alt-Broyles did with what Walter did, as they both did what is needed, and they went very far in order to help their sons and to keep them alive. The “how far would you go?” question gets asked many time in Fringe. But this has to be the biggest one of them, is Alt-Broyles going to go that far to save his son, will he destroy and collapse both worlds by destroying the machine in order to save his son?

It is clear that Alt-Broyles was the center of the show, and that the episode really revolved around him, but this doesn’t mean that Walter and Fauxlivia didn’t have scenes together, as we saw an amazing scene between the two of them. So all in all, it was a strong episode, it answered some questions while it raised some more, will certainly make everyone eager to catch the upcoming episode.
