"She hangs out with me, so she must have some sort of..." Oliver trailed off, a small smile on his face. "She must be crazy to put up with me," he muttered then realised that he had spoken out loud.
"Evidently she has excellent taste in picking her friends." He quickly corrected himself, beaming at the girl. "I'll go and apparate to her place and see if I can get her here. You should stay put until we return, okay?" He pondered this for a moment, then rummaged around in the pockets of his robes. "Now don't take this the wrong way but we both know that you might change your mind until I get back. So take this." He produced a couple of coins from his pockets, everything he carried with him that night - which was embarrassingly little. "You'll need it if you stay on the run. I'll be right back."
With another smile for the girl, Oliver disapparated.
