I knew I wanted to check in with Hannah and Tara after the last full sized issue of BCBC ended with Hannah watching Tara with Jacob, and this seemed like a good spot to do it. It fell in nicely with the timeline. So, a bit of a minor diversion from focusing entirely on the Nakamuras, but it tied in nicely with the overall story.
Also, hopefully it helps to show the time progression from the first part of this issue being on Halloween (around BC8 and BCBC1) to now this part of the comic taking place a bit later (after BCBC2 and around BC11).
