I'm not sure if that would be as impactful it would make sense that it's someone that has known the MC a bit longer.
I actually think that it's none of them that is the mystery e-mailer.
You have to think, that non of the so called potentials have all the info. Remember the MC most likely did not have his computer or laptop as a child. One he and his Mom were poor, hence the reason for filing for child support and having to live with Monica.
So saying that Elaine or Bella are potentials, you have to remember, they wouldn't have Monica's info but they could have the MC's.
Monica never had the MC's info, only her own. That goes for Jolina, who had neither even if she maybe a potential gold digger.
Even the MC didn't have Monica's info, or his ass would have kept in contact with her, even after Dad took his ass away.
That leaves the only potential person with the capacity to obtain both info's...….Jenna!! She of course wouldn't be able to have complete access using her Remotex, but she would have installed a minor version through a backdoor on his laptop.
I think she was the mystery e-mailer, and I think she only had noble intent to bring her brother back. She looked up to him and he protected and stood up for her as kids. She wanted him back home (didn't expect to fall in love with him).
I think (as she herself said) that she's a mastermind, and as such she made sure to cover her tracks.
She most likely used a collage professor to actually e-mail both, giving her the info on both.....so that MC and Monica could arrange the visit.
It would also explain why the description of the person doesn't really match anybody, giving the current story so far.
Now we're getting close to an update, so we'll have more answers.....and questions, I'm sure.
I'll tell you this though, it sure is fun speculating...…………………….Peace!!
