Hello hello I'm in your asks once again lol-
Anyway I'm just curious on how you think Alyona (if she was alive of course) would initially react if she found out that Tatiana had kids of her own (aka Titanium, Sonya, and Rosie) and maybe other members of Tatiana's family finding out about the 3 daughters that are very important to Vinyl City via Titanium ruling in place of Tatiana once she retires, Sonya being the drummer version of Kul Fyra of her own band, and Rosie being the #1 Artist aka the Beloved Idol of Vinyl City.
Of course Matevy (I may have spelled his name wrong-) would not be allowed to be anywhere near the daughters, especially Rosie since she's the youngest and the most impressionable due to her innocent nature. If he even attempts (which I doubt he would) to go near Rosie then everyone would know and Titanium would have to restrain Sonya and her bandmates along with Rosie's boyfriend Azul (who can get pretty dangerous since he is a dragon hybrid-) from jumping Matevy while she has her security escort him out. Poor Rosie would be very confused though-
Also maybe Alyona also meets Olive and they chat and all that, and Olive would be pleased that her and Tatiana's daughters are getting along well with their grandmother. Rosie would always be happy to see her grandma when she comes to visit :3
(meant to answer this earlier woops)
Oh Alyona would be absolutely ecstatic to be a grandmother! Also, if Alyona stayed alive, Matvey have never laid a hand on Tatiana. He definitely would not have been a good father still, but he would not have been physically abusive at least. I would still see Tatiana keeping him away from her kids and family though.
But back to Alyona. She would absolutely be super happy to have grandkids and would spoil them so much! She'd even spoil Olive when her and Tatiana started dating. Maybe she might have been able to change Matvey's mind about some things, but I doubt that.
If your Tatiana is a transwoman like mine is, then Matvey would probably say things behind Alyona's back to Tatiana about having her stop pretending to be a girl since Olive would need a strong man/husband. If your Tatiana is a cis woman though, Matvey would make some lesbiphobic comments about a family not having a father is the worst thing that can happen to kids.
So yeah, no matter what, keep Matvey away from the grandkids. It's not like he would want to be near them anyway. He wouldn't say shit if Alyona was around so at least if the grandkids wanted to meet him for some reason then Alyona would stay by his side the entire time.
Alyona would be very proud of Rosie, Titanium, and Sonya. She probably wouldn't be able to provide them with much in terms of gifts, but you better believe she takes up the stereotype that grandmas never let family go hungry! She'd make all kinds of delicious foods and treats for the kids when she comes to visit of if they visit her! Maybe even making them some clothes or teaching them to control any possible fire powers.
Speaking of powers. I personally have it so the time powers only show up in biologically male individuals, but if one of the 3 daughters have time powers like Tatiana then I can see that being a very rare instance of the time powers going to a girl. This alone would probably make Matvey reconsider some of his world views as he would want to teach his grandkids how to properly manipulate time.
So if Alyona is alive and well, there is a possibility that Matvey actually becomes a better person. Or at the very least a decent/okay person. Still definitely not great, but LEAGUES better than the OG timeline where Alyona has died. I still wouldn't trust him alone with the grandkids as he can still be a huge misogynistic asshole who does not like kids, but at least he isn't beating (or trying to beat) the shit out of children anymore.
But yea! Alyona would be a very positive light in Tatiana's life and with her family!
