Shoot her!

You pull the trigger, firing blindly at your foe. "Agh!" She screams, releasing the other end of the grapple to grab her other arm. "Drop it," you say, gesturing towards the grappling hook, "or I will kill you."

Hana regains consciousness, her eyes opening to take in her surroundings. She's on a rooftop, it's dark and cold and... wait, wasn't there... scenes start to flash back to her as she remembers about the encounter with Widowmaker. About John's sidearm being taken. "Oh no," she thinks. "John?" She calls out into the darkness. "John, where are you?" That's when John's head peeks around a corner on the stairwell up to the roof.

"Right here!" you reply. "If you have a moment, can you come help me with something?"

As she rounds the corner, she sees a most peculiar sight indeed: Widowmaker hogtied with the rope from her own grappling hook, John towering over her, sidearm in hand. "John! I'm so glad you're okay!" she exclaims, running over and wrapping you in a hug.

After you explain how things went down and what happened after she went out, the two of you turn your attention once more to your prisoner, who glares at you with pure hatred. "What are we going to do about her?" Hana asks.

"I've been trying to make her talk and give up the rest of the details of the operation. Like, who else was coming, what the plan was, et cetera," you explain, "but so far I've been unsuccessful. Any ideas?"

Hana smirks. "Oh, I believe I know exactly what you've been doing wrong."
