zeph's dad's side runs a local plumbing company called cobain & sons that has been in bar harbor for decades now and he's mentioned at least one uncle who helps with the business but it's open that there's more. they're all kind of standoffish and in competition with one another on the cobain side. zeph's mom's side hasn't really been fleshed out other than there's a lot of them and they're all located between bangor and mount desert island.
