Brother-in-law.

Jen parked the car in the parking lot of the "shop" that Lucas was talking about. They had gone there to get the car for the race in the first place but Jen thought it was just a normal garage initially only to be surprised by Lucas when he took her to the isolated road where the street race was going to take place.

Lucas draped an arm over her shoulders once she got out of the car and the two of them went into the shop.

"I brought back the car, with another one on top of it," Lucas said and tossed the car keys towards one of the mechanics in the shop.

"I'm assuming it was a victory?" the mechanic said as he looked at the car keys. He was familiar with Lucas as he was the only other friend of Brian who was interested in street racing. 

"It was, where is my car? I'm starving, I want to go have lunch," Lucas said as he looked around the shop. Lucas was clearly in a good mood and had even gotten more talkative than he normally was.
