Ghost, being a wraith hybrid, was used to people being freaked out by his looks and powers, so when you came over and talked to him like you'd known him for years he was taken aback slightly.

He didn't understand why, but sooner rather than later, he got used to it and considered you to be a... friend, but he's scared of losing you.

"I still don't understand why you talk to me.." Ghost muttered as he looked at you, wanting a reason.
