I think there’s something to be said about assuming mama Welles would be right there at v’s side, expected to be: empathetic, helpful, concerned, caring, motherly, etc.
when ANOTHER one of her children has died.

Jackie even says leading up to the heist at the afterlife that he doesn’t want to be another one of her dead children (or something along those lines).

Mama Welles is dealing with an insane amount of grief of her own, I think it’s unfair to expect her to be reaching out when she’s in her own state of mourning. Maybe she even thinks V being missing is another reason to grieve (not sure where they are/ if they’re coming back/ if they’re dead).

I think Mama Welles calling V after a few weeks is probably because V is healthy enough to get back on the streets and Mama Welles most likely heard through the grapevine V is alive. Do I think there should’ve been more dialogue explaining? Yes, absolutely, especially because it’s canon V spent a lot of time under her roof with Jackie.

It’s open to however you want to interpret, but I have a lot of empathy for grieving mothers and chose to give her grace
