A lesson in solving relationship problems?

A trial in Fredrikstad, Norway had a rather unusual turn today. A woman was sued by her boyfriend for stabbing him twice while sleeping. During his witness statement, the man took everyone by surprise, when he turned to his girlfriend, the defendant, and proposed to her. The only one who didn't seem surprised were the defendant, who answered with a loud and clear 'yes!', whereupon the trial continued as normal. The woman was sentenced to 6 months in jail, and the judge congratulated the couple with their upcoming wedding.

Am I the only one who sees the clear errors here?
