At the Temple, R.J was pacing back and forth.
"It couldn't be." She said, "There's no way it's them, it's just a coincidence."
She heard a knock on the door.
"Come in." R.J said.
The door opened and Luz entered.
"Tenzin said that he wants to speak with you." Luz said.
"Thank you for letting me know." R.J said.
Luz left and R.J looked at the door.
"She looks just like Camila."
R.J shook her head, it can't be them. She left the room and went to find Tenzin.
"Yes, Tenzin?"
"Ah, R.J, old friend, I called you here because I wanted to ask you for a favor."
"What kind of favor?"
"I was going to ask if you would help me give the Avatar a display of Airbending."
"Gladly."
R.J got into a stance and started displaying her bending. She moved her arm out, sending a powerful blast of air out. R.J made a sweep with her leg and made a powerful blast of air.
"As you can see, Korra, the point of Airbending is to move freely." Tenzin said, "Now, today, we will-"
He heard a crash and groaned.
"Today, I will be dealing with whatever that was." He said, "R.J, will you help the Avatar while I deal with that?"
"Sure."
He left and R.J looked at Korra.
"So, Avatar Korra-"
"You can just call me, Korra."
"Okay then, Korra, what can you tell me about Luz and Kim?"
"Not much to tell, they were found by my parents as babies and then we basically adopted them."
"And... how old were they when they were found?"
"They couldn't have been any older than a few months, a year at most." Korra said, "Why?"
"No reason, I just... am wondering something." R.J said.
'Is it possible? I need their DNA to be certain, that alone will be difficult.' R.J thought.
R.J looked around and saw Kim and Luz walking around the edge of the island, right on the shoreline. She walked over to the two of them.
"Hello." She said, "I was wondering if I could see your bending in action against the Avatar."
"Sure." Luz said.
"Wait, why?" Kim asked, "Is this a test or something?"
R.J decided to do what she does best, something she has mastered over her... line of work. Lie.
"Yes, as I said, I come from another realm, and have rarely seen such strong bending from two youngsters."
"Okay, let's go, Luz."
The two of them started to have a mock battle with each other, a few pieces of hair falling off. As long as one of those hairs matches Belos or Camila, then they are the lost princesses.
