Harry was apparated back to the weasleys by a girl Tonks. Emma waited to everybody left.
"I know your here Emma." He said. Emma shimmied off the cloak.
"Did I do it right?" She asked
"You did it right." Now all we need you is at the Battle." Dumbledore informed her.
"May I ask how did you deflect the killing curse?" He asked anyway.
"I uh don't know I just did. I didn't do any spell I just stood there and like an invisible barrier formed." Emma admitted.
Dumbledore nodded with that twinkle in his eyes.
"Well it's time for you to be needed somewhere else." Dumbledore puts the cloak back on her and the time turner.
"Ready dear."
"Ready." And Emma was swooshed into another time again.
