I'm reading the manga (hence a more free form writing and lack of punctuation, I get that) and I have this passage (slashes indicate bubble breaks):
A: それじゃあ 確認 / 作戦開始は暗くなってから
B: 私は「Robots」の材料を集めて回って ここの地下に転送
B: Aがそれを準備してくれる / だったわよね？
Context: A and B will later steal a bunch of machine parts and machines to make the "Robots" and cause ruckus with them, all in one night.
So far this is what I think this passage means, roughly.
A: In that case let’s confirm, / the operation starts after it gets dark... by that time...
B: You A will have made preparation for transfer of material for "Robots" that I gather in the basement here, won't you?
I have a problem with two things here.
One is this line
Literally: Transfer to basement here of "Robots"'s material I (will) gather by visiting several places.
which I don't know how it works out grammatically. I'm assuming it's a fragment being completed by the next bit. Also I'm assuming 私は「Robots」の材料を集めて回って ここ is some kind of preposition but I'm not sure. The "V-te form ここ" for is weird to me.
The next bit
Aがそれを準備してくれる / だったわよね？
Literally: A (will) for that do the preparations for me / it was am I right?
ties into the previous one with それ referring to the transfer (this might not be a term to use for transporting matter IRL, but it's a term often used for teleporting stuff in universe) of material.
Now if it was just Aがそれを準備してくれる I'd say this means just "A will make preparations for that", meaning this will happen in future or is being done since it's non-past tense. What is confusing for me is the next bit
since as far as I recall だった is a past form of だ and as such tends to not be appended DIRECTLY on to the verbs. So I'm guessing this is probably a separate sentence or separated by a comma or something. But still why is it in past form when the action should probably happen in future? Basically what am I missing here?
Now that I have typed the above, I guess the last bit could be reffering to B's entire recounting of the plan. A sort of:
That was it wasn't it? / That's all of it right?
asking for confirmation if she has the plan right.
Basically I'm asking how does the bolded line above work from grammatical standpoint and am I wrong in my interpretations.
Also sorry for being a bit more open ended in my question than I was supposed to be.
