I wouldn't be frustrated OOCly nor would Rin be ICly. She's lost like 2/3 of her original students already haha. I understand though it just might not be a good timing for it any longer. Shardless is the new cool huh? In the end, it's your call. I wouldn't be opposed to it because of the CR opportunity it provides with the memory sharing.

When do you think it would be a good time? I'm not sure if she could travel that far south to visit Rin who I think will be stationary though I could probably swing a visit somewhere. Shirou is in Caer Scima and she does need to confirm he's still asleep/not gone as well.
