It would have been a lot easier to simply threaten him at gunpoint, she thought, as the barest hints of a scowl began to seep into her tanned features. He could be dreadfully stubborn when it came to lending out his help; just about as stubborn as she could be, which was both good and bad when dealing with one another. His words stir a little irritation in her bones, but she brushes it off with a light snort. She figured he wouldn’t give in so easy.
Her eyes cast beyond him to where his ship was currently docked. She had watched him as he came off the ramp and was only minimally surprised it wasn’t his precious Black Pearl. It dawned on her he must not have figured out how to release the vessel from her father’s bottled collection. That was a little fact that she, quite luckily, knew about.
“—I see you haven’t freed The Pearl. If you’ll help me I’ll tell you how to get her out of that bottle she was put in. Is that a little more to your liking? Because if not—” she digs into the satchel that’s been hanging over her shoulder since their conversation began and procures a tattered doll that resembles a crude likeness to Jack. A voodoo doll. “—something very bad just might happen to you.”
Jack should remember well enough how the doll worked.
Just because she had a gun didn’t mean he didn’t have one within reach too. He has no problem pointing a gun at a woman, just ask Elizabeth. They were two sides of the same coin essentially, which tended to be more problematic than helpful most times, but at the absolute least it was amusing quite a lot. Except when she was impersonating him. Then Jack was not amused at all.
The ship he was using was getting him by until he could figure out exactly how to free The Pearl from the damned bottle holding it hostage. Only good thing about it still being stuck in there was that blasted monkey still was. The monkey Jack could deal without. But the ship currently under his control was simply a means to an end until he got his beloved vessel back, which would be soon if he could help it. Maybe. He’d figure something out.
Now she had his attention. It hadn’t even occurred to him that she’d know a way. She was Blackbeard’s daughter after all, of course she’d know all the tricks to his trade. But suddenly this deal got a whole lot sweeter. Now he was sorely tempted to join her after all.
Then that damn doll. Easy way to get an anticipatory flinch out of him.

“You wouldn’t. I’d do you little good if you stab that a time or two and I’m off bleeding, love.”
