Jenner's anger had reached the brim. When she was called to come down for dinner, she decided to call her sister and her husband. She had been looking for a way to disturb them from their fun time but couldn't find one so when she was called for dinner, she found that as a nice excuse.
Tina had wanted to call them but she felt they would be busy so she decided to leave them be but Jenner who could hear them play from her room decided that she must disturb their exercise.
She had gone to knock and told them that dinner was ready. She never in her life expected that Dylan would shout at her. Though Dylan didn't know who it was, Jenner didn't care. Dylan had yelled to her and she was upset about it.
She locked herself in the room refusing to come down for dinner. When Tess asked Tina to go up and call Jenner, Tina went upstairs and came back after a few minutes saying that Jenner said she was sleepy and would wake up to eat in the middle of the night, which was a lie.
