I think people are either just taking the OP too literally or ignoring everything the book actually says.>>101838011>>101841606
Like she says she pretends she straight up has no clue about other dimensions at all (though she has been to others, just not Earth), but then the literal next page shows she actually IS ignorant about how certain things work.
It's more like she's pretending to be more helpless than she is (which I guess is an issue on its own), rather her being a super intelligent 4D chess master who knows everything about Earth already the way some people are taking it as.
Basically she wants Marco to feel like he can "save" her since she knows he prefers having control over situations, which then came back to bite her in episodes like Blood Moon Ball when she wanted not to be saved. Which is retarded in its own way.
