Keeper Unpronounceable: "We're just checking in... our clan member isn't in trouble, are they?"
Josephine: "Let's send an elven messenger to talk to them nicely."
Inquisitor: "Sounds good. I'll consider it."
Leliana: "Let's send an elven envoy to do something nice for them."
Inquisitor: "Sounds good. I'll consider it."
Cullen: "Let's send a battalion of troops to assure them all is well."
Inquisitor: "WAT."
"Nonono, Keeper, we didn't capture the member of your clan, we swear. We just escorted her, you see, helped her on her way into a safe location. We even locked the door to make sure she was extra extra safe!"
Edit:
Cullen:
"I have another great idea! Together with the battalion of heavily armed soldiers we send them a box containing a letter from you. That letter will have to detail exactly that your totally not our prisoner, best written in your blood, so they know it's absolutly from you. We should also have a couple of elven slaves carry the box, so that they know how sympathetic we are to elves!"
