This sounds perfect. I can see the upset, especially if it was just when Lara was taking on the reigns of matriarch it wouldn't have made for a smooth transition.

I think Lara probably did reach out and Corrine was so fucked up at that point she just wouldn't even hear of it, and just kind of ignored the attempt. Which probably adds to why she's rather terrified of the moment she comes across Lara now.
