This is a longer chapter review post than usual, because we have to discuss again how Doll knows what she knows.
Doll briefly describes her own death and the deaths of the other first string members of the circus, making them sound like mere victims at the hands of our earl and the Phantomhive servants.
Of course we know that our earl didn't kill her directly, but he orders Sebastian to do it. And our earl only orders it when she rushes to attack. She also knows that "Father" Kelvin and Joker were also killed at Kelvin's manor.
Undertaker and real Ciel watch the manor burn down, and Undertaker collects Doll's body. Doll's not giving details, which she probably doesn't have. Either that, or she doesn't describe it in full detail simply because we already saw it happen (though there's an interesting bit of info she has that we don't... yet). Since William was already on the scene and Ronald shows up pretty soon, Undertaker has to wait for them to leave before he can collect bodies. Kelvin's head was crushed under Sebastian's foot, so he probably doesn't have much in the way of cinematic records. Joker just bleeds out, so he probably does.
The rest of this is also information Undertaker must have given her. Well, all of it could have come from him. As @diakitty pointed out in a comment on a recent post about Doll's knowledge, Undertaker knows the strengths of each Phantomhive servant. So, even without reviewing their cinematic records, he could likely figure out who had killed whom.
There's one other person who could have passed along some of this information, at least to real Ciel and Undertaker, and that's Tanaka. @thesustainedworldatransverse points out (same post about Doll's knowledge) that Tanaka isn't shown as one of Doll's enemies. He was at Phantomhive manor that night, but his main duty was to keep Lizzie from knowing about the attack. He doesn't kill any of the circus members.
I don't think Tanaka has spoken to/with Doll. Also, Doll says she was killed by "Ciel Phantomhive" but without quotations. Real Ciel has reclaimed his birthright, to some extent, and the Lords of the Stars are not supposed to call him Lord Sirius anymore. Presumably, they also aren't supposed to call our earl Ciel.
Notice that we have seen real Ciel with Polaris, and he's talked about having either Polaris or Vega serve him as a butler. But he never suggests that for Canopus/Doll. Not for her to be his servant at all. I suspect that Doll doesn't know that real Ciel is her Lord Sirius. She might still not even know there are twins.
She continues with Beast's death with a description likely to have come from Undertaker, not Tanaka. Tanaka would have explained how there was an explosion. Undertaker, who sees scraps of remains that are burned and might have residue from flour on them, would be the one to suggest she'd been fried.
But poor Jumbo! Finny destroyed Jumbo's body, including his brain, but he was not quite dead. Tanaka wouldn't know that detail; if he did, he would have finished the job. Likely, only Undertaker realized that when he collected their bodies.
Since Tanaka didn't kill any of the circus members, and he wasn't at Kelvin's manor, Undertaker wouldn't need to mention him. And she'd never met him, at least not before real Ciel returned to Phantomhive Manor, if even then. I still don't know if she's aware of real Ciel, since they've not mentioned each other or been shown in the same room. Therefore, I think that's why she doesn't list Tanaka as an enemy, and why he's not shown. This keeps Tanaka's true loyalty as a secret, for now.
Doll wants Snake to help her get revenge on the Phantomhives, which would start with Finny.
Now we need Finny's side of what happened that night. He can explain that they were being attacked at the manor. Because Doll doesn't say where any of this took place.
This is a great setup for either or both of them -- Snake and/or Finny -- to go into flashbacks of how they ended up joining the Phantomhive household.
Then Snake has a big decision to make. Ultimately, I think he will either stay with Finny and the earl... or just walk away from it all, like when he decided to leave the circus. He might decide to help Finny save these kids... and then just quit and go off on his own, with just his snakes as companions.
If Snake left, it wouldn't necessarily be considered a betrayal....
