I dont find she the kind of lier woman. Or exagerated. He is suffering, and he speaks the truth.
She's a woman who lost her husband in a duel, rightful or not. OF COURSE she calls Ulfric a murderer and traitor. OF COURSE he, in her opinion, just came in, shouted and that was it. She affectuated. I would probably think and say the same thing, if I were in her situation, and thought it had been better if my husband had declined the challenge and lived.
For, if you ask the court wizard, she said there was a challenge. If you talk to Torygg in Sovngarde, he says the same.
Funny, this thread was about if anyone likes Ulfric, as a person and/or character. Now we're arguing about his actions - again... :/
