Each one of these six issues concentrates on one of the FRINGE characters, from Olivia to the cow that Walter keeps in his lab! The very first issue has a brief tale of Peter Bishop in Bagdad, then it's a stand-alone story about a hit woman which is so-so. Then it's #2, with Agent Broyles and his ex-wife and family, #3 has one with Astrid Farnsworth. Then, #4 has one of the more interesting back-stories, that of Nina and how she became William Bell's left hand and why she's such a hardened bitch. Yes, #5 has the cow story and #6 has a forgettable story about Olivia training in the marines. In fact, the second story in #6, "Yucatan", is a tale that's more appropriate in TALES FROM THE CRYPT or some other horror anthology series-- it deals with ancient aztecs and zombies and has absolutely nothing to do with the "Fringe Universe" (either of them!).
Granted, this series is a step above the first FRINGE comic series but it still has a long way to go.
