John’s fury
Even though John was aware that Donna was sorry for what she had done, the fact that she had cheated on him did not change the truth. After all they had been through, he couldn’t understand why Donna felt the need to cheat on him. Nothing was sincere at the time.
He felt as though he’d lost contact with her, and seeing Donna just added to his fury and grief. Considering his situation, Donna had to leave with a heavy heart. Although John thought Donna’s finest moves were behind her, this was not the case.
