Yep, that’s her! I don’t remember Alex’s last name and can’t be bothered to go looking for him at the moment, but I remember seeing probably half a dozen photos of him and he was always wearing a light blue long-sleeved button down shirt and khaki pants. Always.
As for who got the short straw in that relationship, Alex isn’t what I’d consider a catch or anything, but he’s not hideous. Kinda plain, really thin, glasses. Looks like your stereotypical high school nerd character, except he’s like 30. Of the two, I’d say he definitely got the worse deal. (But it’s Allyson so the bar is really low.)
