You know who's always at the mall? Brooke. You know who knows Gabe better than most people at school? Yes, also Brooke. And Gram, but he's his brother and doesn't count.
So as she's leaving work, she spots the twin to her boyfriend (she can tell them apart by their walk alone) and falls in step beside him.
"At the mall? Are you a pod person?" It's not as if Gabe is a terribly social person.
