Z is for Zone

Lukas was in the zone.
He had that feeling like he got when he was 'running', but here he was, sitting on the Monohan's couch, waiting for Charlie. It had taken some meddling and threatening from Lexie to get him this far. He had asked Charlie out on an actual date that didn't consist of ten minutes in their Janitor's closet. His nerves were on edge, and he was getting a bit agitated with the way Charlie's little sister kept watching him with that knowing look. Overall he was filled with an excitement that increased tenfold when he saw Charlie.
