Sisters?

"Yes you are," said Elspeth.
"No we're not," said Nissa.
"You two have to be," replied Elspeth.
"She has green skin," Nissa said.
"So," said Elspeth.
"She's a zombie," retorted Nissa.
"And your dead on the inside," smiled Elspeth.
Nissa Revane glared angerly at Elspeth Tirel.
"She has organicly infused metals in her body," said Nissa.
"Well, you have the heart of a golem," Elspeth said just as Karn walked by.
"Hey," Karn began, "some of us do have feelings you know."
"Oh! Sorry Karn," said Elspeth.
"So what are you two talking about?," asked Karn.
"One second Karn," Nissa started, "I'm from Zendikar, she's from Mirrodin."
"You were BORN on Zendikar. You might be mirran. Your parents could have been mirran planeswalkers," smiled Elspeth.
"No they weren't," replied Nissa.
"But what if they were and you were born on Zendikar, but they left you and you were adopted by another elf family," said Elspeth, still smiling.
Nissa closed her eyes, shook her head, and sighed. Karn looked at Nissa, then to Elspeth and again asked:
"What are you to talking about?"
"I'm trying to explain to this airheaded white knight that I am NOT related to Glissa Sunseeker," explained Nissa.
Karn looked over at Nissa, confusion playing across his face.
"You and Glissa are not sisters?," asked Karn.
Nissa buried her face in her hands.
