This follow-up to last season’s “Peter” flashback episode revisits a poignant period of time for both the Bishops and Olivia
Tonight’s Fringe is a do-not-miss, revelatory episode, crossing time and space and allowing us to see Olivia and Peter as children. The hour is crammed with references to previous episodes while adding a great deal of vivid detail to the series’ fundamental relationships between Walter, Olivia, Peter, and Walter’s wife, Elizabeth.
I don’t want to write anything more, lest I give something away about the episode called “Subject 13.” But how much more strongly can I say this? Don’t miss it!
Hardcore Fringe fans will agree that season 2′s “Peter” was hands up, down, and all-around one of the best hours of the series. The great news is that tonight’s follow-up episode, “Subject 13″ (which references the test subject number assigned to young Olivia), will rank right up there with it.
"Subject 13" showcases Torv, Noble and Jackson's performing abilities in ways sci-fi serial dramas rarely try. In the tradition of such dramas, the episode answers some questions while raising others, and is both effective and affecting as a mystery. It's accessible to the casual, occasional viewer, but won't upset or annoy the diehard fan.
Simply put, Fringe fans, you must tune in to tonight's episode.
