Seeing that Draco was so lost in a book (since when did this happen?) and it was obviously Draco, Blaise picked up his book and drink to sashay over and plunk himself in the chair opposite his former classmate.
"I hope whatever it is you've got is sufficiently lascivious to warrant such undivided attention, Draco," he drawled, "as I'm sure I'm far more interesting than anything a book could provide." Slouching and crossing his legs he took a sip of his coffee and smirked over the cup, waiting for the surprise to register. Zabini was back, and he had been far too long away.
