I really enjoyed Morrigan's conversation about the ring.
"Morrigan: I think you are... too important to risk. If you were captured, however, I could find you with this.
Warden: So you're giving it to me purely out of practicality?
Morrigan: (...) You have supplied me with equipment before. This isn't so very different, is it?
Warden: I'm glad to see you care.
Morrigan: Now you're mocking me! Do you want the ring or not? I'm tempted to simply keep it.
Warden: Thank you for the gift."
I like it because Morrigan's dialogue in Inquisition will sound like a call back to this.
"He will think this means I miss him, of course. He will be insufferably pleased with himself. I hope you appreciate this sacrifice, Inquisitor."
