He's QUITE a bit older than she is, and he basically disappeared from UES/NYC in 2007. He's back now and has only been back for about 3 months. So while his parents were fixtures, they definitely took a step back when he disappeared. so the families might know each other - and the grandparents probably heard of him. His bio is here, if helpful.
Luke is relatively friendly, very driven, perfectionist, geeky, and fiercely loyal. But he is a workaholic/ has no chill. So with the opening coming up, he'll be at the bakery from 4:30AM until 6PM every day, trying to get it off the ground. He is happy to work his connections to get it successful as fast as possible. is he trying to get a story in Time Out about a banker turned baker in FiDi? you bet.
Umm otherwise, he lives in FiDi with his girlfriend and two cats.
