As you watch Chad walking you'll notice his gait: not very extended from hips to thighs. His paces are short for such a tall man. He doesn't have any swagger side-to-side. Very deliberate walk, arms mostly stiff, with a little movement at the elbows, but not flexed. Deliberate, but not overly in a hurry. Ever. Also, his shoulders and neck are broad, but not extended. I've always noted that he looks like he's hunched over forward a little. You can see that his posture isn't chest-out and thus his neck slightly bends forward making his eyes almost always looking slightly downward (especially noted in the courtroom where he's just sitting there). It's a tall thing, but it's how he has always walked.
Compare that last portion of this video

to the storage unit video

at 1:37 - 1:42 is the second man carrying out a heavy tote. Note the same shoulders and head. Some guys would pull shoulders to carry it all with their back. Since he doesn't, the tote is in front of his legs. He almost has to go bowlegged because the tote is in the way. But the steps are the same pace and gait as in Chad's walk from the courtroom.
Compare that to the man assumed to be Alex in the video (0:56-1:03). He's also tall, but not as tall as Chad. His shoulders (hidden a little by the jacket) are squared off. Head not tilted down forward, and even though carrying the heavy tote and tire, he's using his arms more by pulling his shoulders back. Also, between carrying out the heavy tote and tire, he comes back in, you can see his shoulders are not slouched and hunched forward while carrying nothing. Alex's forearms are extended outward at the elbows at this point as well. He walks more openly and nearly bow-legged kicking legs out at the knee. 1:18-1:21 in the storage unit video also shows the two together. The second man bringing the bike in again, hunched over, not just because of the bike, but the legs are also short steps even with longer legs.
We know now thanks to the probable cause affidavit that Chad was there with Alex when the Nov 26th well check was conducted. They knew each other. The likelihood of Chad being the man with Lori on Nov 24 (two days earlier) is solid. The likelihood he was there with Alex Oct 28th is as great.
So... what else does Chad know. This walk to the car and day without Lori have to be weighing on him. I imagine he's weighing his options. Now also hearing that the court doesn't recognize their commitment ceremony as a marriage might give him an out.
