- Nightmare Fuel: All of part 2 of "Our Unfamiliar Home", no exceptions.
- And everything in part 3 of the same arc, at least before the duos meet back up with each other.
- Tear Jerker: Oh so many, especially in the recreation of Equestria. Twilight and Jack watching a corrupted stallion die after helping them; Rainbow Dash having to deal with the horrible orphanage Scootaloo once lived in, and finding Scootaloo's ghost in the process; Applejack and Rarity being scared out of their wits and nearly having a Heroic BSoD by this timeline's Ponyville hospital...and that's just in one chapter.
YMMV / Crossed Paths
