I, unsurprisingly, went with the Nephew. Family comes first, after all.
Though I would still pick Madison and Jaime as well. And, while they’re not my absolute favourite characters, Rachel and Jillian have grown on me.
Overall, I like the entire cast. There’s only about one/two people who I legitimately dislike, and I can always just kill them off halfway in my playthrough if they grow too unbearable.
