Robin's Pov.

It has been a week since Terra has been encased in her stone prison when we defeated Slade. We finally got Beast Boy out of his room and out of the tower to get some pizza. The waiter brought us our vegetarian pizza and walked away. BB just sat there and looked at the pizza but didn't make a move to take a piece. We all missed Terra but none of us missed her more than BB.

BB looked up from the pizza and seemed to be looking at something off in the distance.

Out of no where BB said, "They kinda look like Terra."

All of us turned our heads to see what he was talking about; there were two girls walking towards the table. They stopped when they reached the table.

Looking at BB, one of the girls asked, "Are you BB?"

We all looked at BB as he answered, "Yes, why?"

"We think that you can help us find our sister, Terra."

At that moment we all looked at the two girls closely and noticed that BB's earlier statement was correct - they did look similar to Terra with just a few differences.

The first girl had black hair with fair skin. She appeared to be 5'4" - an inch or two shorter than the other girl is, and her eyes were a pale blue. She looked to be 16 years old. Around her neck, she wore a necklace with a light blue teardrop the same color as her eyes.

The other girl had golden hair with a tint of red in it. Her eyes were a deep blue-green that reminded me of the ocean. She also appeared to be about 16. Around her neck, she also wore a teardrop necklace but hers was different. Hers was red with blue waves in it.

Cyborg was the first to stop staring at the two girls and said, "We didn't know she had any sisters. She would have told us if she did."

"Well," said the taller girl, " We haven't seen each other in about 5 years so that might be why. Anyway, we need to find her soon so ask whatever dumb questions you have."

"What are your names?" Starfire asked, looking excitedly at the two girls, eager at getting a chance to make new friends.

"My name is Danielle," said the girl with golden hair. She was the one who had been doing all of the talking so far.

"And my name is Skyler." The other girl added.

"Why haven't you seen each other in 5 years?" I asked.

"To make a long story short, our father - if you can even call him that," Danielle said with disgust in her voice, "kept us locked up in a prison below the earth's surface. We finally escaped a week ago."

"Why would your father keep you locked up?" Starfire asked with shock written all over her face.

"That is another long story and after we find our sister we might tell you it." Danielle said in a monotone voice that Raven often used.

"We need to find Terra now, and we will answer more of your questions later, so please take us to our sister," she said in her same monotone voice.

"Um, well, you see Terra has kind of been turned in to stone after stopping a volcano that was about to destroy the whole city," Cy said nervously.

"Yes, we know that already. When our father was distracted by Terra, we were finally able to escape. When she opened the earth she freed us, and we don't know where she is because she is underground somewhere and our powers don't really work to find things down there," Danielle explained.

"Well, follow us and we'll show you the way," BB said standing up, the pizza long forgotten.

We took them to the entrance of the cave before the girls stopped. The five of us turned to look at them wondering if something was wrong.

"Will you wait for us out here? We need to go in alone. Bringing her back will make it too hot for you to withstand. The pressure will instantly kill you." Skyler said in the same monotone voice Danielle used earlier.

"What the hell are you talking about?" BB yelled.

"Why do you think we came here? To pay our respects to our deep sleeping sister who you all think is as good as dead!" Danielle said calmly but with such force it could crush a diamond.

We all stood there, too shocked to talk as we watched Danielle enter the cave. Skyler stayed and looked at us for a moment before saying, "It will get warm out here, too. When you feel it cooling down, come in to help us. All of us will be to weak to come out on our own - especially Danielle and me." With that said, she turned around and followed Danielle into the cave.
