Speaking of banter, I wonder if Morrigan will have anything to say about Cullen since they can be seen out with our Inquisitor at the same time? Especially if your Warden was a female mage and your Inquisitor is a mage courting/flirting with Cullen. My Amell romanced Alistair as well, so I could imagine comments like:
Morrigan: "What is it with mages and templars? You oppose each other and yet you're quick enough to lay with one another the minute the Chantry's back is turned."
Morrigan: "Ugh, not another mage going googly-eyed over a half-witted Templar."
Morrigan: "It seems you have quite the magic fetish, Ser Cullen"
Cullen: "W-what?!"
Morrigan: "You were once infatuated with a certain mage of the circle in your younger years, were you not?"
Cullen: "I, uh... that's ancient history! I was young, it was a foolish crush..."
Morrigan: "I bet it just killed you to learn of her involvement with another Templar"
Inquisitor: *SMACK DOWN!*
