Their travel was made quick by apparating, but Gwen made certain that they didn't go directly to the source. They needed to be at least a certain ways away so that they could prepare themselves mentally for what was to come. Gwen made sure to explain some very important things to Harry.
"Listen, you're going to hear a lot of things that don't necessarily make sense and honestly I don't have the time to explain them to you now, but you just have to believe that no matter what we end this today."
He nodded, glancing apprehensively around their non-descript surroundings. The walls were gray here and there was rubbish in the corner. It smelled just a little bit like the inside of something brand new and plastic, like a giant trash bin that's never been used. The room was empty and he had to wonder where in the world he could possibly be.
Gwen didn't seem too concerned. She had her hand on the rusting black door knob of a gray door, paint chips falling where her fingers brushed it. She just wanted this whole business finished.
She steeled herself against what lay ahead of them and opened the door before her. Harry was close behind, his hand trailing the door as it closed behind them with a definitive click.
