Oh, no! While Kent does help me greatly with my sleep, I actually have a small Rattata blessed by a god who ensures I sleep peacefully.

[That is sure a sentence that he just said. Dimitri tactfully does not mention that Byleth got him that little Rattata.]

[Which might actually make her double from god.]

As for Silkie, she often just takes pleasure in helping others and receiving thanks. You would actually be doing her a great service if you allowed her to assist you, and you were appreciative!
