I cannot believe you thought Darren didn't know what Eolys fluid is. It was obvious to me that Darren didn't believe you understood it properly which is the reason he was asking you to clarify.
As for copying out of books or off the internet, knowing Darren this will not be the case. His head is full of this stuff, admittedly it does get a bit jumbled sometimes but he is a mind of information> Myself and other respected members of this site will testify to that.
