In the background, Sakura ended up restored to the Tōsaka family, and she's the one who ended up taking on some of the traditional magus responsibilities I didn't want to be forced into writing for Rin. Which might be a bit mean to Sakura, but in-character it shows a hell of a lot of trust in her little sister by Rin, and she seems a bit more suited to both dealing with kids and organising a demesne.
