there are some details in phoebe's info, but essentially their dad was a philandering two hit wonder in the late 80s/90s with some acclaim but nothing that's a big deal now. i imagine him to have been a sporadic presence in his kids' lives growing up, he'd sort of drop into town, assume the role of the fun parent and then kinda leave the actual responsibility to their moms? how your character feels about that to this day is up to you - i saw you were looking for angst and drama, so you could absolutely play up how kind of shitty that was? their dad was well meaning but just like, not great at being a parent. phoebe herself didn't even know about her half siblings or seek them out til she was a teenager.
