I don't see how there could be a part 2 ? Most all paths end with Julia being Pregnant.... Unless they do it couple years later ? LOL then we'll see what the baby is and from whom ...LOL !!!
IMHO Part two is all about Julia. She could be marrying either Peter or Cornell or... maybe Rufus and Martin throw their hats into the ring too! All the guys could be wooing Julia and competing against each other for Julia's heart! Each guy would bring something different and good to the table, for Julia to consider.
Peter brings steadiness, though boring, she could always sneak away and spice things up when she has the
"need"!
Cornell brings recklessness, eventually, Julia would tire, competing with his other ho's, and being passed around like a party favor. While the sex with Cornell is on another level, IMO it's not enough and he's only a phone call away.
Rufus while apparently wealthy and hung like a horse with the stamina to match. The jury is still out.
Martin, less is known, but that mystery could pique Julia's interest, especially as long as he's packing!
