in chapter 60 pages 17-18 , undertaker said something about an "eccentric bunch" who wanted to see the effects of the bizzare doll as weapons , any ideas ?
Eccentric bunch
Too many ideas, but the biggest one I have is that the queen (or John Brown, perhaps on her orders) put together a shell company or some organization to be what Undertaker calls this “eccentric bunch”. So, Undertaker might have done this for the queen without knowing it. And the main reason I’ve considered this idea is what she says to John after our earl makes his report. She thinks the idea of them is dreadful... but would be delighted in having them as "allies".
It’s possible she knew what Undertaker was up to with corpses on the Campania before our earl even went there. Notice that she didn't send him on that assignment. In ch51, he reads about Karnstein Hospital in The Times, and Lau gives him the scoop about the hospital bringing people in (human trafficking) through the docks for experiments. He sends Sebastian to Karnstein Hospital to gather intelligence, and he comes back with information about the Aurora Society, which will have a meeting on the Campania. That's the ship Lizzie just said her family was taking on a trip to the US.
It's entirely possible that the queen didn't really want our earl to know about what was expected to happen there at all, not even the Aurora Society's meeting. He just happens to get wind of it. I always thought it was a weird move to have Double Charles join as travelers on the Campania, away from both Victoria and John Brown, but apparently on her orders... for the anime adaption Book of the Atlantic. Double Charles are not on the ship in the manga. I assumed it was simply because they are popular characters, but the decision might actually be some little hint that the queen is somehow involved in what's going on there.
Anyway, Double Charles in the movie adaptation makes me think Victoria sent them there to keep an eye on our earl, as soon as she found out he was going there to investigate the Aurora Society. Who told her about that? I have to assume John Brown, since I don't think our earl gives her any heads up about going. Not in the manga and not in the movie. Of course, she does later send our earl to investigate Sphere Music Hall, which is also associated with the Aurora Society, but maybe she involves our earl this time because the shady organization is no longer doing things that appeal to her. She's now afraid of things like rebellion.
Honestly, the movie did absolutely nothing to explain why Double Charles are on the ship, and they don't seem to bother keeping tabs on our earl, so -- ugh -- bad writing. Anyway....
If the "eccentric bunch" doesn't belong to the queen, like a group of generals or something, idk who else they would be. Definitely people interested in military research, like the queen is... but maybe not British. Possibly German? 🤷🏻♀️ Them being secretly connected to the queen makes the most sense to me, so far. If they are from another country, then Victoria must be pleased that our earl messed up the experiment and told her about the possibility of such "animal weapons".
I wish I could give you more, but I just don't have anything... other than: IF they do belong to the queen, they would be an interesting parallel to Mother3's Pigmask Army, the military might of King Porky. The Pigmask Army takes Dr. Andonuts' instructions for making Fascinating Chimera and starts running their own experiments to create their own versions. And their versions are absolute abominations. They are the ones who turn Claus's body into the Masked Man. King Porky calls him his "robot". That's why I expect Queen Victoria to be pleased if real Ciel becomes her new watchdog....
