So....
Imagine if grant and terry were dating around the time he rolled the die another day. And he saw grant shot him. And he had zero context on the situation so he thinks grant will eventually be against him in the future and to make that situation hurt less, he starts distancing himself and they end up breaking up by saying some choice words.
And then when they are kidnapped by willy a second time, and Willy puts the collar on them, he type of now understands how he would die and that it really wasn't up to grant. That the only thing making grant kill him was that it was the most effective way to stop the teens which was an objective given to him by the collar.
And then they are in their cells and grant is apologizing and terry forgives and tells him he knew it would happen because of what he saw in the dice but this context is way more forgivable than what he thought would happen. Then terry brings up that what he saw in the die was what made him break up. Then grants like "Oh"
And while grant feels guilty when trying to be friends with terry because he put a bullet in his head, they do slowly move on and are besties again because they are in-laws now.
