No matter how many times people confuse you and Parvati, you are going to make your mark where it counts: by being yourself.
Unfortunately, you get so wrapped up in these thoughts that a lot of time passes, and you discover you've been pacing around Diagon Alley very dangerously. You realize you should get back to Weasley's Wizard Wheezes immediately.
On your way, you run into Harry, Luna, and Neville.
"What are you doing here?" Harry asks, alarmed. "You were supposed to be at the Burrow with Ginny and Katie."
Pulling out your wand and chanting, Sonorus!, you exclaim "I'M PADMA!!!!!!" so loudly and furiously, everyone from Buenos Aires to Makati can hear you.
That includes Voldemort by the way, and a poor girl in Forks, Washington who is so frightened by your howling, she gives birth several months early to an imprinted kid.
