-Subaru would have never expected to see his mother again. He knows that it’s normal for his kind to not get to have any relationship with their parents, but for the short time he was allowed to be with his mother, he got painfully attached. He’d be beyond grateful to be able to be with Christa again, but unfortunately, he mental state is another matter entirely, and there’s a good chance she won’t remember him well enough to treat him anything like she did when he was younger. The rejection would hurt, of course, but Subaru is well aware of exactly what kind of trauma his mother has gone through.
