Aiden looked for a suitable place to where he could deal with his personal business.
"Hmm... I can't do it here. I need somewhere isolated lest people found me and think that I had gone nuts."
Aiden made use of his mind and orchestrated his plan of how he should deal with the lady ghost in the simplest way possible so as not to risk attracting the attention of other people towards him.
After all, it was not like he wanted to be seen by other people talking to an invisible entity out of nowhere and end up being branded as a crackhead in the process.
It was something that he did not wish to gain on his first visit to the mortal realm again after spending a few days at the Underworld. He did not want to have that kind of reputation associated to his name, not now and not even in the future.
