That has bothered me as well. At first "his heart dropped" because he saw her car there at her home when she should have been at work. And then the next time he references it...she would have been home from work at 7-730 when he went by.
Unfortunately there are quite a few things that make us go hmmmm
1)going to her home and seeing her car when she should be gone...then she should have been home by then.
2) Past tense...lots of it.
3) Talking about being "terrified" with no emotion.
4) Him explaining that he got the picture at 12:52 but that it could have been sent much earlier because it takes so long to upload. What? Why an explanation of time?
5) Burning "legal documents in the middle of the night". She texted that she wanted to be there to see it. Why? Who burns class schedules?
6)Does he usually stay with her when they go out at night? They have been together 6 yrs. just asking?
7)Intuition tells him she is close.....
8)Why not call her work if you are texting her over and over again? Simple call to work to see if she is there.
9) She wasn't being forced to move to Colorado. Forced....odd language. She wasn't being forced to marry him, move etc. Odd
10) Again...past tense referrals....lots of them
11) Hats were off of bedpost where she kept them and pencil holder was tipped over. He explained those things as being the only signs of things disrupted in her room. Why explain it away as the dog? odd
12)Why would he be in such a panic. Put his key in the door and go directly up to her room? odd
13) Keep her smile in your mind and don't worry about her. odd statement
14)Kept saying "to be honest" when asked about a few things like burning the documents and a couple other things. hmmm
Anyone care to add the things that I have missed?
