Ch 40
Ch 39 recap: Juergen (black hair) and Joachim (blonde) both work for "the Sia"; Juergen was the spy Shadow who had infiltrated the Knights Templar. The Sia is trying to prevent the Lord Of New York (female dragon sleeping underground) from waking up, while Knights Templar is trying to... Kill the Lord of New York? It turns out that Juergen is actually a DRAGON! Child of the Lord of New York, but he has never changed into dragon form in all 32 years of his life and doesn't want to.
Read up to s2e3 in raws, wait till more have come out 0ast that (like, s2e5 or something). At that ep in the raws the Templar Knight red hair caught him, locked him up, as he's escaping he sees what I think is Juergen bloody and hanging in another prison cell.
