Doctor Dedalus. Batman. Batwoman. Gaucho. She's definitely the reason they're all there. Father, lover, lover, successor.
But what about The Hood? Why is The Hood there? I think it's possible to take Gaucho's words literally here, even though he's naive to The Hood's real motives. A super-spy. Working for T.H.E.Y., who we still know next to nothing about but who one imagines are a bit of every great pop culture British spy organization, in a world of super-heroes, probably founded by Sherlock Holmes at one point.
He works for a guy called Matron. What I'd never bothered to look up before is that the British Armed Forces never abandoned the term "Matron" and it's been used for male as well as female officers. (Also, of course, as I think has been mentioned elsewhere, Matrons are commonly associated with boarding houses. See: Batgirl's mission in Batman Incorporated # 9.) We can surely bet that Batgirl's mission to England will continue with the Brit angle Grant has been stringing along throughout his run, and it's likely enough beats from Knight, Squire, and highly likely The Hood will pick up there. I recall Paul Cornell wasn't permitted to use Dai Laffyn in his mini-series either ... so I wonder what the odds Dai turns up in the ninth issue will be.
But if Gaucho's remark is semi-literal, or meta-literal ... The Hood too is there because of Kathy Kane. Who we know from The Kane Affair was involved in all manner of espionage in her life, between flings, artistic endeavors and her marriage to Nathan and subsequent widowing and drafting by Spyral. I had to wonder if The Hood knew Kathy Kane personally as well. (Of course, if Kathy = Leviathan, that would explain the meta-literalness of the phrase as well.)
Lastly. Three PSY-OPS agents. What Batman does IS PSY-OPS. Using propaganda in warfare. Using bats, urban legends, rumor, darkness and fear to weaken his enemies. Colonel Kane called them "deep black", and black in US PSYWAR is used to designate the branch that is specifically used to deceive an enemy. Obviously deception is nothing new to Batman, Batman's enemies, Morrison, Morrison's run on Batman, yadda.
The question is, why would deceivers be the ones used to effectively be put on guard duty for Otto Netz? Highly trained guards can be found elsewhere. Do they need to be trained to recognize and look for deceptions? Possibly. Are they learning from their prisoner? Possibly. Or is there something more there?
Otto's conversation with Kathy seemed damn near a psychic chat in the middle of that acid trip freakout in the 60's. I don't believe he's psychic, but rather that Oroboro might give the psychic tools to somebody. OTTO is a palindrome as well. The old man - the fake Netz - spoke with his own voice, and only toward the end did we "learn" that it was a tape recorder.
I'd posit (today, anyway) that Netz was using his shadowy ability to speak through or control the fake Netz and then the tape recorder was more than just a little bit of duplicity to throw them off his trail having escaped.
We'll find out more soon. Like how Netz, Hood, Kathy and the super-spy angle ties with Leviathan and the continuing themes of "Super Drugs" and slavery we've been seeing.
