dipper & mabel aren’t 1:1 parallels of stan & ford - sure, it might be easier to spot similarities between dipper & ford and mabel & stan, but there are some really important traits that dipper & stan / mabel & ford share
one of the biggest ones for me that i wish people talked about more is their inherent attitudes towards trust
ford is not a naturally paranoid person, doesn’t have much experience with other people, and is a really bad judge of character. that’s a big part of why he was so easy for bill to manipulate - bill could just show up and be like “i’m a muse !!” and ford would believe him, because that’s the type of person he is. i don’t think he ever actually got better at figuring out who’s trustworthy and who’s not, either - “trust no one” is just an inverse of “trust everyone” born of trauma
mabel is, in practice, the same way. i can’t really give a particular reason that ford is so trusting - it just seems to be part of his personality - but for her it’s that she sees the best in everyone, no matter who they are or what they’ve done
stan & dipper are the opposite. they’re both inherently distrustful of other people. again, they have different personalities and different reasons for this - stan is a professional conman and is fully prepared for anyone he speaks to to be the same way, while dipper is more like “what if they’re actually 4,000 termites in human clothes” - but the end result is the same. they’re significantly less likely to take things at face value than their twins
anyways in relativity falls mabel should be the one who built the portal i said what i said
