There are just a few gaps left in Season 1 overall such as what house were Constance, Tate & Addie living in BEFORE the school masacre in 1994? I mean there had to be a time when the Langdon's moved OUT and the Harvey's moved IN and then back out again (solo Larry) after the fire. It seems like the latter is incorrect information as Tate is murdered (DBC) in the room that later belongs to Violet. So as far as timeline concerns go, I believe the correct order of events is that the Langdon's moved back IN to the Murder House after the fire and the deaths of Larry's wife and children (Lorraine, Margaret & Angie) and so, Larry never left. The confusing part to me is the dinner scene on that evening BEFORE the massacre in 1994; which IS NOT at the Murder House.
