"Ms. Grey!" Or he guessed that she was Mrs. Summers now, Or Mrs. Summers-Grey or maybe - Jean? Nope, he couldn't call her Jean because he just - couldn't. It was a bit weird.
He still gave her a big grin though because she might be married and have a kid, and sure she might have been one of his teachers but she was still foxy. Not to mention she was terribly nice.
"Belated congratulations on your baby."
Should he have said that before now? Oh well. He'd buy the kid something nice for her next birthday.
