Okay, so I was looking through all the chapters of Resurgent and looking at comments. I noticed a popular one was in Chapter Six. A lot of you tried to correct me on the age. Yes, I made a minor mistake and made Tris seventeen, but I figured between Divergent and Allegiant she could have possibly turned 17, however that is not what most of you corrected me on. You corrected me on the age gap between Tris and Tobias. Tris was 16/17 when she died Tobias was 18. To keep Tris's body from decaying, so they could work on the Resurgence Serum, Caleb and Tobias placed her in a freezer or something that freezes her completely, like an ice cube. She was dead, her aging stopped, while Tobias's didn't. The first chapter takes place 3 years after Tris dies making Tobias 21, where Tris since she was dead, hence hadn't aged, she was still 16/17. Sorry that was long, but it was sort of irritating me so I wanted to set things straight.
