I actually forgot to answer your question...
So, like I said about Agents of S.H.I.E.L.D., we are able to watch any episode we wish, but as far as Fringe, we are on my third run and my parents' fourth run.* Right now, we just finished Season 4 (so, we just watched Brave New World: Part 2) for, like I said, the third time.
*By "run", I mean third time of me watching it. My parents watched it once without me, and then I started watching it over and over ever since.
Question: What's your favorite Walterism, or even Fringe moment?
