[Details are the bane of a liar. Give too many and the lie starts falling apart at the seams. Give too little and people feel like you're withholding and will start probing for further details, which is where Molly is right now, caught on the cusp of humoring the lie and kicking it like a hornet's nest, unconcerned about what might fly out. He's not considering what the slow dissolve of the lie might do to Allura- she'll recover from it. He'll help her recover from it. It just has to end first.

His insight allows him to see that her confidence is shifting and it bolsters his. He takes the bottle from her by clasping his hands around it and her hands for a lingering moment, since that triggered something before, and when the bottle comes away, she has a couple of silver in her palms for her trouble. She's faltering and he's committing.

He removes the stopper and sniffs at the contents.] Y'know, maybe it would be cruel to remove you from this life. You seem to be flourishing here, and I know the hassles of being a princess are too much compared to the simplicity of town living.

[He replaces the stopper.] I could always say I didn't find you, unless you're starting to think this could really just be a spell. I can't force you to do anything, but... Just be happy. Be truly happy. 'Cause you can't be happy if you're wondering what's real or not.

[Never mind that he's the one who came in and smashed her reality with a hammer. There's no being delicate in this.]
