After having stood in front of the door of the kitchen for over some seconds not replying to all what Rogers had just said to her, there were literally so many things and questions that were actually going through Berny's mind at that particular point in time where she was actually standing at the door.
As Roger kept on looking at her with a very surprised look as he was not expecting to have seen Berny at that particular point in. That was also because, the moment he had gone up stairs to her bed room to look for her, Berny was actually being in a very deep sleep.
As he has now come down stairs in order to make sure that, he starts to make some break fast for both him and Berny. Since he had already considered and read from the manner in which Berny was sleeping very early that morning when he had entered the bed room that she was actually being very tired at that particular point in time and she really needed food at that particular point in time.
