[Missed call. Missed call. Missed call. Missed- Lucas would have answered if it hadn't stopped before he could reach for his phone. It's probably about 'his shite' at Brandon's flat that he still hasn't picked up due to lack of time. Driving to LA in the morning, driving home in the evening every day is more inconvenient than he's anticipated it to be.
Besides, it'd look weird if he showed up and Britten was hiding somewhere in the shadow... He dials and waits and waits and waits-]
