He was the one who first noticed something shady was going on with the investigation into Lucius' murder.
I don't think I quite saw the promo...the one with Luke and Mary's actors just called it the Batbike.In that promo, did they call Kate's bike the "Batwing??" I couldn't tell, but if they did that's a big FU to Luke if he ends up being named after the motorcycle...
