Why not? Bella was around the house and my MC has told her the will conditions. She also had access to the father and to her sister's files.
Jenna and Jolina require more of a stretch than Bella. After all, Bella certainly knew the MC's father while for Jenna and Jolina we don't know so. Also... Jenna? Nah. Jolina? She puts effort in the relatioship with the MC while she's also willing to break up.
More or less that. I admit that it could well be that Bella is NOT the secret 3rd person, but as hell she banks on the MC getting the money and spending it with her and sabotaging her competitors.
She may not be THAT gold-digger, but she is a gold digger.
with me you break trhough an open door, for me Bella is satan.
I also doubt that she has a reflection in the mirror.
she behaves incredibly manipulative with both MC and her sister.
as she says at lunch with Mc, "but a girl has to think of herself sometimes too"
and in my opinion Bella is thinking of herself even before the death of MC's father
Could be Jolina. Maybe she was using Bella (we still do not know the full story of Bella and Jolina's relationship), and is now using Jenna to progress her plan.
How many of the girls know about the father's death and the will? Depending on who the third will participant is, she may have a hard time explaining why she did not tell you (unless not telling MC before the will reading is one of her conditions).
Jolina as the second gold digger is a great candidate
the fact that she brought MC to Theresa and then Bella describe the possible second gold digger to us just as the religious fanatic stinks a lot ..
and being a computer specialist too, she may have taken Jenna where she wanted, including live sex, the perfect opportunity to appear as a victim and tie MC and Jenna to her.
moreover this could also explain why Elaine wants to avoid Jolina, she could suspect something about the relationship between her and Bella and therefore not get noticed
