Adrian takes a moment to rummage through his blurry memories that night, feeling all the more shaken by his obliviousness.
He has long braced himself for something like this - facing the consequences of his ignorance, that is. Ever since he admitted his feelings for Cassidy, he thought that the very least he could do to keep her by his side was clean up his own mess. He is prepared to take any bad consequence as long as she stays.
Adrian would accept it if Cassidy had come to hate him so much. It would be okay if she gave him the cold shoulders. He would understand if she could never forgive him for everything he did.
However, Cassidy has been kind to him - like she has always been.
