Prologue: Mother Earth Strikes

'Quickly, Superboy!' Superman yelled, while he flew down, 'the building!'
'Got it,' Superboy screamed, 'Kid Flash help me!'
'On my way, SB,' Superboy heard Kid Flash say it in his ear. Quickly Kid Flash removed the people who were near the building, while Superboy tried to hold it as long as he could.
'KF, are they gone?' Superboy yelled, feeling the adrenaline more than ever.
'Almost, SB, give me some more time!'
'Hurry the fuck up!' Superboy screamed.
'Relax, Sups, I got you,' he heard a friendly voice in his head; M'gann. He looked up and smiled, she was helping him stopping the building from collapsing on all the people. She smiled back. Superboy could not understand this had happened so quickly. A few earthquakes, everyone had thought. But it seemed like the core of Earth herself was shaking. All around the world were major earthquakes. Superheroes were powerful and strong, but Mother Earth was an opponent none of them could defeat. Now they tried to help and save as many people as they could, but this building had at least thirty floors and was pretty heavy – even for Superman and his clone.
'You got it?' M'gann asked him. Superboy pushed a bit harder against the building and moaned.
'I'll try, you go help them!' she immediately flew away. There were still so many people down there. Most of them were heavily wounded. Superboy felt the building leaning more and more. He could not hold it for much longer.
'I cannot hold it anymore!' he yelled.
'This is Batman to Superboy, do you reach me?' Superboy heard in his ear.
'I reach your Bats, but make it quick!' he said panting.
'I want you to push the building back, it will still fall your way but than you at least have a chance to save some people, copy that?'
'Copy that!' he pushed a bit against the building, 'Superboy to everyone, did you get the message from Batman?'
'Yes, copy that, hit it Superboy!' Nightwing said in his ear. Superboy pushed a bit more against the building, but suddenly he heard something.
'No, no, no - wait, please wait! O, God, please,' it was a girl, yelling it.
'Superman, did you hear that? Superman! Super-'
'Superboy, do it now!' M'gann said in his head. He had probably just imagined it, so he pushed a bit more and flew away. Than suddenly someone jumped out one of the windows of the twenty-eight floor and fell down. It was a girl, the girl who Superboy had heard, he just knew it. She was screaming, while she was falling quickly.
'I got her!' Superboy screamed and flew towards her.
'Hurry, Superboy!' he heard M'gann say. And he was fast. He flew to the girl and caught her in his arms. She was panting and shaking. She laid her arms around his neck, while she was still panting. Superboy did not see the look of jealousy in the eyes of M'gann, right now he had to take care of the girl who laid in his arms. Suddenly she screamed and grabbed him even closer. Superboy looked around. The building was falling right on top of them. He looked the girl in the eyes.
'Do you trust me?' he asked, he spoke quickly, 'I have to try something, but I'm not sure-'
'I trust you,' she said. He had to try, there was no getting out, not anymore. Even quicker now he flew down, within a few seconds the building would fall upon them. When he reached the ground, he gently stopped and laid the girl down.
'Ready?' he said, while he bend himself over the girl. She looked over his shoulder.
'Absolutely,' she said with a short smiled, she laid herself close against Superboy as he wrapped her in his arms. He was strong and very muscled, she on the other hand was pretty small and was completely hidden behind him. His arms were tightly wrapped around her.
'Superboy!' M'gann screamed and ran towards him.
'M'gann, no!' J'onn screamed, but he was to late. The building crushed down, crushing M'gann with it. Superboy tightened his arms around the girl even more. She set her nails into his chest and was screaming of pain. Superboy was pushing to hard and was even pushing harder. She fell something snap inside her. A fierce pain like a stab of a knife hit her right side. The building had almost fallen completely. She could not take anymore.
'Let me go! Let go of me! Come on!' Superboy opened his eyes in amazement and with that, his arms opened and let the girl go. Did she just call him 'Connor'? The girl was heavily breathing and grabbed to her right side. She backed off, just a bit. But that was enough, a small part of the building hit her head and she blacked out. Superboy stood up and lifted the girl up, the building laid around him. He flew to the others, carrying the girl in his arms.
'Is she-' Kid Flash began.
'No, she just blacked out,' Superboy said, 'and it's my fault.'
'Don't be to hard-' Superman began.
'No, it is! I broke her rib, or two, I think one, and than she backed off…' he sighed and looked at the girl, 'I'll take care of her.'
'Superboy,' Superman sighed and stroke his hand through his hair.
'No, you said I have to take my responsibility, and I will,' Superboy said fierce.
'He's right,' said Batman with his dark voice.
'Where's M'gann?' Superboy asked, while he looked around. Than he saw the face of J'onn.
