Editing A Beacon for Us All (section)

==Trivia==
*Together with ''[[The Show Must Go On]]'' and ''[[Ouroboros]]'', these episodes are the only ones that never mention the episode's name or a variant of it in it's script. The episode's name is most likely implying Melanie's appearance as a Beacon to Snowpiercer's citizens.
*[[Melanie Cavill]] is confirmed to have survived, using the suspension drug for [[the Drawers]] to help keep herself alive as she searched for ''[[Snowpiercer]]'' in a [[Track Scaler]].
*Melanie is rescued by ''Snowpiercer''.
*''Snowpiercer'' is revealed to have a crane arm controlled from a observation window.
*Melanie appears in the present for the first time since ''[[Many Miles From Snowpiercer]]''.
*The events of several past episodes are referenced, including Melanie trapping Layton in [[the Drawers]] in ''[[Without Their Maker]]'' and the destruction of [[The Aquarium]] in ''[[Into the White]]'' as well as Wilford leaving Melanie behind to die in that episode. While helping Melanie to take the train, Javi mentions how he was in the bathroom the first time that she did it unlike this time. Melanie also wears what appears to be the same sweater from the end of ''[[First, the Weather Changed]]'' and she makes her announcement to the train in the same way that she did as the Voice of the Train in [[Season 1]]. It is the first time since ''[[994 Cars Long]]'' Melanie talks on the Public Announcement system.
*Melanie betrays Layton, forcing him to retreat to ''[[Big Alice]]'s'' [[Big Alice (Engine)|Engine]], while Wilford escapes from his prison with the help of his supporters, including [[Mrs. Headwood]] and [[LJ Folger]].
*Despise Melanie saying she went across the Bering Strait, the computer map in [[Setting Itself Right]] and the Track switch signal, detected in France during Wilford's chase of the [[Pirate Train]], shows that she went east to Europe.
*The cellars had 246 bottles of champagne left, before the party.
*[[Bess Till]] and [[Miss Audrey]] begin a romantic relationship.
