[There is no need to ask what those "things" are. Knowing who Mordred was, and having glimpsed some of Gray's struggle, Rin knew enough to piece it together. It's something that Tohsaka herself could never really understand. At least not in the way that people with similar experiences could understand each other. Not only that, but Rin considered herself relatively insensitive to the plights of others by default. Never could she make a connection so profound.]

At least you had her then, for a time. To know that even across space and time that you are not alone. As a mage to an apprentice of a mage: I am always open for questions.

[What goes unspoken is: I take this as a duty of obligation knowing I am trying to make sure that the world who would teach you in my stead does not return.]
