I think it's a broader issue with this game in general. Your same considerations could (dominance apart) could apply to Wanda and Angel, to Porche (was it the name of the escort?), maybe to Zarah, to the blondie at the carnival, to Natasha ecc...
The story is a bit unfocused and sideplots get a lot of space and make the general plot feel a bit disjointed. If i can move a point to the otherwise very good game it is that.
It does feel a bit like four (overlapping) stories in one, which is part of the reason it's got so big:
- the inheritance (LI: Bella, Elaine)
- helping to save Monica's business (LI: Monica, Zarah, Angel, Wanda)
- helping Katie get revenge on Natasha (LI: Katie, Debbie, Lily)
- getting Jenna out of her "hermit" lifestyle partly by investigating the e-mail (LI: Jenna, Jolina, Theresa)
