Enemy of My Enemy really amps up the season and mythology arc. Written by Alison Schapker and Monica Owusu-Breen and first aired on 20 January, 2012 .

Last episode ended with the reveals that the Observer (Michael Cerveris) has told Olivia (Anna Torv) she has to die and that the alternate version of Broyles (Lance Reddick) is heavily involved in the shapeshifter conspiracy, and is aiding a familiar, evil, and previously dead face, David Robert Jones (Jared Harris) who is captured by Fringe Division this week. (He’s alive because Peter wasn’t around to stop his escape).

Nobody on the other side knows who Jones is, except for Peter (Joshua Jackson) who is still there with Lincoln (Seth Gabel) following his conversation with Walter-nate (John Noble).

Jones is a little unnerved that Peter knows so much about him, and in Peter’s knowledge may help them save the day, but for one little mistake…

As this episode comes to its conclusion we learn that our universe’s version of Nina Sharp (Blair Brown) seems to be working with alternate Broyles and that the drug and treatment she’s been exposing Olivia to may tie in with their plans.

Lots going on!

We also get to see Orla Brady back as Elizabeth Bishop who crosses into our universe to speak with Walter about helping Peter find his way back home. Something he finally agrees to which is good because Peter is becoming increasingly anxious and fearful about being able to get back to his own timeline.

A well-written episode that moves all the storylines forward and keeps everyone guessing and everything moving.

Forced Perspective while dancing around the edges of the mythology arcs gives us a story of the week. Written by Ethan Gross, this episode was first broadcast on 27 January, 2012.

While Olivia worries over the warning delivered by the Observer about her dying, she and the group get thrown a strange case which leads them to a young girl, Emily (Alexis Raich), who, through her art, can apparently predict someone’s death.

Of course, there’s a connection to Massive Dynamic, but trouble truly escalates when Emily’s latest image shows countless people dead.

But perhaps with help from Walter, Emily may be able to tell them more about the things she sees when she creates her art, and that may give them a way to stop the tragedy that is coming.

This one is a bit of a breather from all the other things that are going on, though it still ties in peripherally with them.

I do like how the characters, in these altered versions of themselves are starting to gel and work together. How is it all going to play out? What version of the universe or timeline will we follow as the series continues? I guess we’re just going to have to wait and find out.
