Hello! Here is chapter three. Please leave a review!

I do not own the Flash or Avatar.

Katara was in tears. She had realized that she was in a completly different universe and there was probably no way back.

"Hey calm down it's Ok." Iris said. It took a second for Katara to calm down. She took a deep breath and stood up. She looked at Caitlin.

"What do I need to do to get home?" She asked determined. Everyone looked at her with a sympathetic face.

Avatarverse:

"Calm down Snoozles. I'm sure that they are fine" Toph said, fed up. Sokka had been pacing up and down the same patch of grass for almost an hour, his heartbeat was going faster than Aang and Katara's when they were kissing.

"Sokka the best thing we can do for them right now is wait." Suki said, even though she couldn't feel his heartbeat she too was sick of him being in this panicked state.

"NO THERE HAS TO BE SOMETHING WE CAN DO!" He yelled at both of them. Suki's eyes bulged a little and Toph got mad.

"ALRIGHT THEN SNOOZLES! WHAT DO YOU SUGGEST?" Toph yelled at him.

"Ok, I know you're both mad but we have to stop fighting for Aang and Katara!" Suki butted in. "Maybe there's someone who can help us. I think that we should go pick up Zuko and Mai like we were going to, maybe they know someone that can help us."

Suki took Sokka and Toph and made them get on to Appa. Sokka and Toph sat on the opposite side of the saddle and Suki steered Appa.

Starling City:

Barry flashed into the Arrow cave and was surprised to see that there wasn't anyone there. He flashed to the Top of Palmer Tech, everyone from the Arrow cave was there, except for Oliver and Felicity. Diggle jumped when he got there and Thea looked at him in awe (she had never seen the Flash before).

"Hey Diggle. Where's Felicity? I need her help for something important." he said

"Felicity and Oliver are on leave. What do you need help with?" he replied.

"I need her to make a fake ID for a girl that fell from the black hole, we need her to blend in until we can find a way back for her to go home." Barry said.

"Ok, then why don't you call her?" Thea spoke up. Barry looked at her then at Diggle.

"She's Oliver's sister." Diggle said. Barry smiled at her then flashed to her.

"Nice to meet you, I'm Barry Allen." Barry said. He flashed to the phone and dialed Felicity's number.

"Hello?" she spoke through the phone.

"Where are you?" Barry asked

"Barry? I"m in Coast City with Oliver" Felicity replied confused. Barry dropped the phone and flashed out of Palmer Tech. He ran to Coast City and went to all the places he thought they might be. Finally he found them walking along the bridge. He flashed Felicity off the bridge to an alleyway then did the same with Oliver.

"Barry, what are you doing here?" Oliver asked him slightly angry.

"Felicity I need a favor" he said. turning to Felicity.

Central City:

Everyone was talking to Katara, Dr Stein was about to go home and see his wife when the alarm sounded, like it did when the black hole opened again.

"What's going on?" Katara asked.

Dr Stein ran back to the computer and looked alarms stopped after a minute. He looked up and said.

"I think we should go outside. A portal just opened for a second, I think something came out of it." Dr Stein said.

"How do you know that?" Joe asked Dr Stein, confused.

"I'm getting the same reading of when Katara fell out of the black hole on a smaller scale, because it just opened for a second the black hole is a minor threat. This smaller hole that opened does not have the energy to become a singularity." Dr Stein replied. Joe looked at him as if he was confused. "It means Barry isn't needed." Dr Stein said annoyed. Joe nodded his head.

Everyone headed outside and Katara followed them, when they got out they all looked up at the sky, sure enough there was a figure in the sky but it wasn't falling like Katara was, it was gliding along the sky, slowly coming down. Katara inhaled excitedly, as if she knew what it was.

"What? Do you know what that is?" Cisco asked her.

"It's Aang!" she said exitedly.
