['Bittersweet' is exactly how he'd describe it, that feeling of happiness knowing his friends would live laced with the bitterness of waiting for them to remember so that he can finally go...the joy of making friends once more, only to know that none of them will remember him this time.

I wouldn't claim to know what you and Hiro have been through together, but he's not alone in feeling sad about not being able to see his friends again.
