I've got it narrowed down to something from early game, since I don't want to unveil the "Child of the Full Moon" business just yet. I'm considering the monster attack at Deidon Hold, since that'll let her know that she's a healer and also allow her to recognize Yuri...And also allow her a healthy dose of "run into traffic" syndrome.

Is there a memory in Yuri's registry that might shake off that 'distant' feeling?
