Found the last two I've done!
Sera: "What is this, that is before me? A Seeker with rage for all to see?"
Cass: "Stop that."
Sera: "Put a smile on thy face, it isn't a strain. If you only frown, then wrinkles will remain.
Cass: "I'm going to hurt you, Elf."
Sara: "Ah, must you wound me so? Fine, one more Rhyme for thee before I go?"
Cass: "If it'll shut you up."
Sara: "Spend less time looking at the ground, at the streets that are paved. If you look up and look around, you might finally get laid!"
Cass: "I. Am. Going. To. Hurt. You."
Varric: "Now now ladies, there's no need to get hostile. Sera, why don't you give the Seeker a few minutes to calm down?"
Cass: "I don't know how much more I can take of this."
Varric: "Don't fret Seeker. She'll find someone wearing a lot of shiny jewels too drunk to say their name straight. She'll be distracted in no time."
Sera: "He's right, just so you know. Now I hope we can go somewhere to go see the snow!"
Cass: <sigh>

Sera: A lovely young lass for me to see. What brings you here to the Poet Tree?
Vivi: I do not think you wish to do this.
Sera: Nonsense, with my little rhymes I love to play. Come, join me on this fine and lovely day!
Vivi: Very well then, since you insist my dear.
Sera: <squee!>
Vivi: I know this game of rhymes you seek. 'Tis not a game meant for the faint and for the weak.
Sera: Show me what you can do. Do you have more wit than is in a shoe?
Vivi: Let us begin.
Vivi: I see a young elf so full of humor and sass. I would be too, if I had no chest and a flat ass.
Sera: Wait, what...
Vivi: Your hair is like brittle straw, though I am sure women in the dark do not see that fatal flaw.
Sera: Hey, hold on now...
Vivi: Now now dear, it is only for a laugh. I can smell you from here, so please do take a bath.
Sera: WHAT?!?
Vivi: What is the matter with this little game? I told you I would win one and the same.
Sera: Wait, but I have...but I didn't...just one second here...hey!
Cass: <doubled over with laughter>
Varric: Ah, Madame, you never cease to amaze me. Shall we be off, everyone?
Vivi: Oui. Little Sera, it was much fun. We should do this again sometime, no?
Sera: <mumbles something not nice about Vivi's mother>
Vivi: What was that, dear?
Sera: Nothing.
