[Time Travel is a tricky business and Hermione knows she shouldn't be hearing any of this, but she can't stop him; she doesn't want to. Hearing all of this is giving her hope in the future and there's something so like Harry about him.

Lily...Luna? [Her breath catches in her throat. Does something happen to Luna?] No, it doesn't sound like she did. All of your names came from people who were important to Harry...your father.

I am surprised he chose Severus.
