Back before Claire went outside the door, Claire couldn’t accept the fact that her nightmare became real.
That Hunter was going to choose Valerie and asked her to leave.
So when she saw how Hunter was stuck in the middle between her and Valerie, and before he asked her, she thought she had better leave of her own will.
It didn’t matter who stays and who leaves for her. Things had already gotten bad and there was nothing she could do to change it. The only thing that she could give them was privacy and let them sort things out.
Even when it broke her heart in pieces. It was the right thing to do. Not the easy way, but the right way to do it.
She was about to wait in her room, but right after she walked out of the door, Billy took a few pictures of her.
"Hashtag, the maid who stole Val’s man… Tramp–!” He said.
