You knew Ghost was a wraith hybrid, you didn't know how but he was. You knew he could get poisoned if he used his powers too much as well.

And, unfortunately, he came back from a mission where'd he had been forced to overuse his powers.

At the moment, you were treating him special with a nice bath. You'd gone all out. A nice black bath bomb that reminded you of his powers, petals that were safe for him, the best soaps you could give him, and you let him just lay down all dazed and giggling a bit.

"Quit touching me like that, it tickles." Ghost laughed softly and almost like a child as he squirmed when you went to rub a loofah against his side.
