Okay, now I’ve warned you. Here are the ways I thought things might end:
1.) Niall would take Sookie back to Faery because she’d been mortally wounded.
2.) Niall would take Sookie back to Faery because she was going to inherit something.
3.) The bad guys would kill her and Bill would turn her at the last minute to save her life.
4.) Sookie would choose to go to Faery for a while, intending to return to BonTemps at some future point in time.
5.) Sookie would get bitten by a were of some species or another.
6.) Something bad would happen to Sam and she’d have to stay and run Merlotte’s.
There were tons more that floated around my head, but these were the forerunners.
