That hadn't occurred to me, but after giving it some thought, it seems unlikely Hunter was involved in Ophelia and Aliza fooling around as kids. For one thing, and I'm not saying it's super common behavior, but sisters practicing kissing each other is a normal form of exploration. Ophelia and Aliza were 13 and 12 (respectively), and as much of a creep as Hunter is, I don't think he would've been interested in them at that age. Additionally, Aliza was overweight for most of her life, which is another thing Hunter doesn't seem to be into.
