Aidan was pacing in what he considered the den, but the realtor had called the "family room", where the fireplace was, waiting for Theo to arrive . Did he feel absolutely one hundred percent comfortable with inviting a stranger into his home? Not entirely; what if it was some crazy fan? While he didn't feel completely comfortable, he also felt like this was the thing to do. There was something about this that felt like he had to do this. Crazy.
When the flames burst up from the Floo, he stopped his pacing and waited, watching a very small gentleman appear. This was it. Aidan wasn't sure if he should smile, for once. Did this man even know who he was? That would be nice.
