LJ and the rest ARE in the EF, but it is at the point where everyone is being moved TO SB. So the line is appearing because they are in the process of being moved to SB. The very next thing that happens is Charming (and others?) finding LJ on the side of the SB road and they take him to the hospital but no one remembers anything anymore.
Possible, RG, though I still think LJ looks like he’s wearing modern clothes in that clip. One of the trademark features of his FTL costume is nowhere in sight. Simplest explanation is that they’re already back in SB when it happens.
This is a dirt road
There is no way to tell what kind of road it is. All we can see is that it’s covered in snow.
