[It isn't really Ari's business, so she's hesitant to say too much, but she feels that she ought to say something.]

I understand why you'd hope not, but it might be easier if the friend does remember. If not, you have the risk that someone else will tell them, or that you'll... react to them in some way, and they won't know why. It'll be worse in the short-term, but if you could talk about it, maybe you could both move past it?

[It's what she would want in that situation, anyway.]

But you said intense emotions - does that mean that the way to beat him is to make ourselves indifferent to everything here? [That doesn't sound psychologically healthy either.]
