After the Warden wins the bout against Myaja and Lucjan, both will admit in subsequent conversation that they learned a lot from fighting against the Grey Warden. If the Warden fights the proving on behalf of Harrowmont and gives the throne to him as well as part of A Paragon of Her Kind quest, Myaja and Lucjan will attack the Warden, should the latter go back to the Proving area and initiates a conversation.
Myaja: "May the Stone honor you..."
Lucjan: "...when you fall."
Myaja: "We were born together. We fight together. We'll die together."
Lucjan: "The ancestors gave us one soul, but two bodies. Everything we do, we do together."
The Warden: "Everything? You mean even...?"
Lucjan: "That's a little personal, don't you think?"
