I grimace a little bit when she calls me 'Master', but shrug it off and go to get her a cup of water, bringing it over for her and holding it myself for her to drink, given that it would be rather difficult for her to drink with her hands bound behind her back. "Here," I say, holding it up to her lips, but waiting for her to close the final inch of distance before I tilt the cup to let the water pour between her lips. Then, while she in drinking the water, I cast Charm Person on her.<br/><br/>(Save DC of 17 for my Charm Person thanks to Spell Focus: Enchantment :D)
