The fifth chapter is more captivating than ever. Claire's father shows a darker side which is most convincing (I found it inspiring and it provides a better insight into what is in store for the rest of the series and the mysterious father of Claire). I love how the characters seem to interact more and more with each chapter (in this one the big highlights are Hiro and Nathan - a quite funny scene- and Peter and Isaac - which provides a very cool way into seeing some more of Peter's awesome power and the best is yet to come).
DL (Leonard Roberts makes his debut in this episode - although he had scenes in the unaired pilot) Niki's husband and a very important character that will drive Niki's story throughout the rest of the volume. His ability is currently unknown although some hints are given in this episode.
The most mysterious character however is that of The Haitian (who appeared in chapter 3:One giant leap). His mystery will be revealed in this volume and in the third volume but until this point (after four volumes) his name is still a mystery.
Finally the first and the final scene are breath taking in the sense that will give you the thrills (especially the cliffhanger).
