Sasappis outfit is different in this episode than the rest of the series.
When Jay leaves the bathroom, he emerges from the door at the end of the hall furthest from the stairs and joins Samantha in the bedroom by the stairs to the attic. However, after their fight, Samantha is now leaving the bedroom by the door previously revealed as the bathroom and heads to the stairs instead of emerging from the doorway previously established as the entryway to the bedroom.
When Jay leaves the bathroom at the end of the hall complaining about no cold water, there is something that looks like a staircase right behind him beyond the door.
Pete (the troop leader ghost) mentions the movie Ghost, which was released in 1990. Later in the series, it's revealed that Pete died in 1985, so he wouldn't have known about the movie, unless in the intervening 30 years of constant occupancy of the house "a living" had watched the film in the house while he was in the room (as any of the ghosts could have) or mentioned it within his hearing.
