The ancient meme-washer starts to life, flooding the chamber with steam. It is like a sauna filled with tiny crawlers, who comb through the assassin's mind, searching for any meme he may have unwittingly picked up on his way and eradicating them. He feels a song go out of his head, a jingle for a soap that hasn't been sold in millennia, a religion, perhaps two, a theory of everything, a new concept of beauty and a recurring image of possibly alien origin, he can no longer remember.
