It’s hard (sometimes impossible) to see the true mechanics of an animal’s gait with the naked eye. It wasn’t until the late 1800’s, through some revolutionary technological advances by Muybridge that we learned exactly how horses’ legs are positioned in a walk, trot, gallop, etc.

I think he thought eventually she’d come back to the group? He never wanted her to leave the company, and he’s self centered enough to believe that he hadn’t burned all bridges the legal stuff. He’s very good at controlling and manipulating the others, so it’s easy to see why he might think he could do the same to Andi again eventually. The email showing she had leverage changed the situation.

Helen said she was at the house cleaning up just 1-2 days after Andi’s death when the box was delivered. Miles said that his “puzzle guy” was barely able to make the five boxes in time for delivery, implying a tight turnaround, and it’s obvious from seeing the boxes that they couldn’t have been made and delivered in just a few days. I don’t think it needs to be stated that the delivery was already in motion when Andi sent the email.

It’s simpler than that, the boxes were already made before the email and murder. It would have been harder and more suspicious to try to stop her delivery.

He never wanted the estrangement between them, she was the one who left the company because he was crossing a line with the fuel. He’s delusional about a lot of things, including thinking he could bring her back into the fold somehow even after screwing her over legally. I imagine he had also invited her the previous year to the “cruise thing” Whiskey mentioned.

This time around, there was a lead time of several weeks or months for the construction of the invitation boxes, so the order was already placed long before the murder. After the murder there would be no reason to cancel Andi’s box delivery, perhaps he wouldn’t have even thought to try.
