[You say only the Whipman can be beaten by words. So be it then, may they be beaten by words.]
Morton smiled. He's not usually one for devious plans but... He's not a fan of his friends (or close proximate, in some cases) being hurt either. "Now, what I'm thinking Chef Niklas, is that if I can get the good captain's help, I'll try to pose as a 'possession expert,' or well, rather, someone who works for one. Spin a good tale about how I've been tracking some possibly possessed items, and how they slowly tend to warp one's mind as they hold them." Morton said, implying the knives. "I can say I've been trying to track down a certain man who holds said items," with that he nods towards Niklas, "and say he was last seen in their establishment. I'd ask them if they'd seen you, and if so if you left any items behind perhaps, never specifically mention the knives but hint to them. Talk about how they drive the user more and more mad the longer they are in possession of them, until the spirit takes them over body and mind unless grievous harm is suffered, or the knives removed. With the good Captain's help, I'd appreciate it if he were to aid in the convincing, maybe with something subtle, or less subtle as he wishes." Morton explained in his typical optimistic tone.
After a moment's pause to regain his train of thought, he continued. "From there, I'd attempt to get the guards to hand over the knives, say something about me having a special container for them to prevent mischief on the spirit's part. You did say you wished them dead though, didn't you Chef Niklas? Well, I suppose I can brew some tea and use some of that nasty black paste I believe Sir Scott still has in his possession. A toast on a crisis averted, as it were. I'd drink mine first, after all the paste won't affect me I believe. I've already died." Morton explained with a shrug, smiling at the end of it.
