Hmm...See, I'd go and just charge her, but I don't think I can get away with that. Technically, if she charged in the direction the sickening ray came from, it could work, but that'd be something the DM would have to allow.  If Lily can't charge her, she'll likely take a double-move action to get to her, but I'll make a post pending a DM decision. It'd be a swift action to switch to Hunter's Sense so she could smell the maid, and a full-round to either charge or double-move.
