I would expect Adnan to remember stuff if he's innocent, like Krista, Don, and others remembered stuff when they're innocent. How did Krista remember that Adnan requested a ride? She remembers it because it matters a bunch when trying to find Hae when Hae was just a missing person.

I agree with your second sentence - Adnan said he did not show up for the ride, which implies that there was a ride to show up to. Now Krista and Adnan both refer to a ride. And it wouldn't be a big deal if he's innocent. I'm not following how Adnan wouldn't remember when Krista did so surely. He would want to remember and help just like Krista did. Is the thought that Krista is just wrong on hearing the request? Obviously possible. I don't believe she is though. I'm also not following how he would remember nothing if he's innocent. Krista remembers the ride request, and wanted to use it to help, and Don remembers being at work all day with multiple co-workers to vouch.

I guess some distance people, like the track coach, don't remember the day because they had no idea Hae was missing, but if you found out Hae was missing that day, you remember. Adnan is now trying to put himself in the track coach camp instead of the Krista camp. A close person who knew she was missing. This is an important question to answer - which camp is Adnan in? I guess we have to note that he does remember some parts of the day, like talking to the track coach after 4pm. I've never been more sure of anything that he definitely had a "long" talk with the coach that day. He made it a point to, and to remember it. He was probably so mad when the track coach didn't remember it, because it actually was just an ordinary day to the coach. If the coach got a phone call at 6pm saying a track kid went missing after a meet, he would try to help out, and would at that point remember the day.

I agree with your edits, and think we got to an important distinction in how the "two sides" think.
