I've watched several of these early episodes several times now, but it's hard to keep straight or remember exactly what happened in which episode.
Beginning with Ep #4, the first post in each topic displays a montage for that episode. The montage for Ep #2 is in the discussion topic for Ep #3 because they were shown together as the second night of the miniseries. And the montage for the pilot is in Part 2 of the discussion for it. All of these montages can be referred to to easily identify each ep and refresh one's memory as to what happens in each.
(And the case of the pilot, Ep #2 and Ep #3 the commercial bumper videos can also help.
)
Also, I've edited out the comments that referred to Ep #3 that were posted in the discussion topic for Ep #4, and they are now posted in this topic.
