"Mr Potter..."
Neville straightens his back, turns and smiles. Waiting at the bar, he's been hunched over his pint of Spooky Porter, not the best choice of a drink when he's already felt skittish. At least he hasn't needed to watch the doors in order to notice Harry enter the Leaky Cauldron. Now if he manages to follow Roger's advice...
"Hey Harry, what's new?" He lets the glass linger by his mouth, then runs his tongue over his teeth, and his hands over his arms, which he crosses slowly enough for Harry to see he's flirting.
