So I have only seen the animal and a few of the early light novels/manga and I just realized that Vassago Casals was a member of the Pk guild, Laughing coffin. I was wondering if

1.) Casals knows that Kirito has been attacked and disabled by Johnny Black, his former guild mate.

2.)If Casals knows that Kirito is on the ocean turtle or is it just a coincidence

3.)This relates to the before mentioned point, Does Casals know Kirito is in the underworld?
