In The Dark/Nightmare Fuel


 * The bus accident for one thing, having three people tossed into the middle of nowhere.
 * Melanie being kidnapped and being subjected to Cold Blooded Torture while locked in a Torture Cellar.
 * Not knowing, if Melanie was every going to be alive, yet alone found.
 * Her family goes through this.
 * Melanie breaking down.
 * Being uncertain if your friend is ever going to be the same, spare a thought for Emma on that.
 * Being forced to face the person who tried to kill you in a cult-like sacrifice, poor Melanie.
 * The details Melanie gives out during her time in captivity in Chapter 55. Geri did recommended hypnosis, which worked... too well.
