Someone unexpectedly showing up makes a lot of sense. It would explain her movement around the stadium, her "antsy" behavior, and her leaving at halftime. I have never thought that when she left her home, with the dog, that she looked like she had any plans for anything more than a drive to see her son play his game. She was not dressed at all as if she was going to any kind of serious meeting with the SEC or anyone else. She just looked like a typical mom out for a day of leisure. I had been focusing on the thought that she got a phone call that was the impetus for her departure, but it may very well have been an unexpected arrival that made her feel uncomfortable. The only thing that makes me think that may not have happened is, if she was scared enough to want her bf visiting her for the weekend, she had her ex, in a public place with other people, seems she would have maybe told him if someone was making her uncomfortable Idk.
