Oregon heard the word about Sakura being awake, thankfully she had received enough treatment for her to regain consciousness to know that she was back home, and not back in Lucifer's dungeon.
Word had it about her rejecting every visitation of the doctors, who came to check up on him, and he could care less what was bothering her in her mind for her to take out her frustration out on innocent phantoms.
He was still angry at her for what she had done to him, if she hadn't locked him up then she wouldn't have been captured by Lucifer and tortured like some criminal.
He stood outside her room, hearing the crashing sounds in her room, and then her yelling to her maids.
"Get out!" He heard her yell, and he's glad that she's back to herself, and had her voice to talk because he needed answers to the questions he had for her, so there's no excuse whatsoever that she would come up with this time around.
