I mean, it's Echidna's library. Beako is contracted to guard the library. Who else would it be?

That's what I mean.

Hasn't he already said(just not to Subaru) that his goal is killing the Black Dragon?

Can't remember. Wonder if Black Dragon and the Serpent are related though.

I assume the Black Dragon is the same as Gluttony's black serpent, yes.

I have no idea how he came to the conclusion that Echidna is her contractor.
What gave that away? Did Echidna mention the book during the tea party? Was it Roswal who said that?

I think he just put 2 and 2 together as Beako said something about "Keeping knowledge was the most important thing to her" when talking about the library's creator and when Echidna was describing what each of the Witch's obsessions was, she said that was hers.
