Cut her loose, and show her who she's dealing with

"Very well..." You reply to elf, earning you a glance of suspicion as you confidently walk up to her with your jagged dagger in hand. You prove that you don't mean her any harm however, by cutting her bonds, and is swiftly rewarded for being so 'easily tricked' as she sweeps you to the floor in a single elegant motion - ending up on top of your chest, with your own blade against your throat.

"Now then..." You continue, once you've catched your breath, as calmly as if nothing had happened. "Now we're on equal ground, so would you mind telling me why you're in such a hurry?"

"That's none of your business, goblin!" She's quick to reply, though you can tell she's confused by your act. She's also shaking in nervousity, knowing your guards are just outside, which is far from the carefree nature that has always been associated with her kind. "Tell me how to get out, and maybe I'll let you live!"

"Not a very polite approach." You tell her, with a slight dismay passing across your face. "And here I was hoping for some mutual understanding."

"What...?" She just stares at you, looking even more bewildered by the moment, and you figure that she might hurt even hurt herself more than you if she's not relieved of that dagger soon.

"Allright, just listen now..." You say, while leaning your head back to keep the edge from scratching your skin. "You're being chased by something, or possibly just carrying a very urgent message. In my politeness, I'm just curious as to what this may be, and figured it could serve me somehow to be of some aid to your cause..."

While you speak the woman just starts to look around her for some way of escape on her own however, as if she finds you much too strange to her to be of any actual use. You take this moment of distraction to roll her over, and you're quite proud of yourself as you manage to trap her as quickly as she had just done to you. Not every goblin could go toe to toe with an elf, which makes you even more certain that she's not actually a warrior at all.

"I'm sorry for that." You tell her as you get back on your feet again, returning your dagger to your belt, and then meet her astounded stare as she pulls herself up to sit on the ground. Even confused and defeated, she still manages well to put up with the most elegant pose. "Now, would you allow us to discuss this in peace...?"
