Return your ward to the Shattrath City orphanage by handing in the Blood Elf Orphan Whistle to Orphan Matron Mercy in the Lower City.
Darn it all! I guess it's time to go back to the orphanage at Shattrath City.
I've had such a great time. You're the best person in all of the worlds, <name>! You're my big brother now!
<Salandria's eyes begin to well up with tears.>
I'm going to miss you so much!!!
