"No worries, Lief," Edvard greeted jovially, "Let me get you a glass, quick." He knocked on the bar to get Sergio's attention, motioned for two of something, a large one and a small one. Sergio, in response, slid two shot glasses down the bar at him: a double and single.
"In fact I have," Edvard said as he filled up the double, so that Lief could catch up to the to of them, "A while ago I recieved word through the grapevine that somebody with whom I went to school in Salem, Massachusetts had taken up the quest of finding me. It seems that he wanted to exact vengeance for me having thrown his wife out a muggle airplane during her assignment to take me down." He grabbed his shot glass, ready to down it, he seems to greatly enjoy this reverie, and a manic light once again entered his eye. "Oh she was an auror," he added, as if that explained everything.
((Edvard went to the wizarding school in Salem, MA, which is briefly referenced in one of the books, however he was born and raised in Barbados. At this point he's about 30 years old. This thread could help on showing everybody his past, which your characters most likely know, but getting us to know it OOC is the tricky part.))
