IGN - After a few interesting developments in last week's story, Fringe returns with a deeper look at the lives of those on the other side. This week's mystery has the team figuring out some strange deaths, as usual. The case of the week carries little weight or interest by itself, but it does serve as an adequate plot device to get our characters into the required situations, and connect the dots to our main story. In this case, we have Walter taking a little trip to the other side and investigating alt-universe related happenings with Lincoln and Fauxlivia. The acting is top-notch, as it usually is, and there are nice spots like Walter's casual line about escorts/prostitutes, but for the most part this story suffers from a "sagging middle" as the script sets things up.
