It was 8 months after the Metarex War and everything was returned to peace, every planet was restored to its original beauty and look and the whole galaxy was safe again thanks to Sonic the Hedgehog and his friends, Tails, Knuckles, Amy, Chris, Cream and Cheese, even the Chaotix, Rouge, Shadow and Eggman were included in the final battle. Few days later, Chris was sent back to his own world by Eggman who made a machine to take him home. During the final battle they lost a dear friend, Cosmo, who made an appearance to their world asking for their help to save the galaxy which they accepted and also wanted to recollect the Chaos Emeralds after Sonic used Chaos Control to send them away during a fight against their leader when in his super form. Everyone were sad and heartbroken when Cosmo sacrificed herself to save the galaxy, especially Tails who he and Cosmo had a really big connection with each other. Their friendship grew nearly every day and they loved each other as well.

Sonic was walking to Tails' House. It was 7:30pm and the stars were bright in the night sky. Sonic never saw Tails for 3 weeks and he was getting very worried about him and decided to check up on him. He then turned up outside and knocked on the door. There was no answer.

"Tails? Are you there?"

Sonic saw the lights on inside the house, so it was a sign that he was home. Sonic then turned the door knob and opened the door. It wasn't locked either. He walked inside and saw the light on in his room. Sonic walked towards it and heard someone sobbing and sniffing. He didn't like what he heard. He walked towards the sound and saw Tails crying, located in his bedroom.

"Tails what's wrong?" Sonic asked while worrying about him at the same time. Was Tails like this for the full 3 weeks or longer?

"Oh, hi Sonic." Tails said when he looked up seeing Sonic standing there with a worried face.

Sonic then saw Tails hugging a flower pot, which meant one thing, Cosmo's seed. Tails was hugging the flower pot really hard and close to his face.

"Tails please don't tell me that's Cosmo's seed." Sonic told him.

"Sorry Sonic but I'm getting the same nightmare over and over again." Tails said to him. Sonic then remembered the memory Tails was referring to, shooting the Sonic Power Cannon to Dark Oak when Sonic and Shadow were in their super form and Tails forced to shoot even when Cosmo was there.

"I'm sorry Tails but we knew what happened back then. Do you want me to help you by any chance?" Sonic asked.

"No."

"Are you sure Tails?"

"Sonic please go! I'm not in the mood to talk!" Tails snapped. Sonic never recalled Tails yelling or doing anything like that to him in his life. Right now Tails was hurting too much inside and nothing was going to heal it. Sonic then decided that he needed more time to himself and check up on him again as soon as possible.

"Um…sure. I'll see you tomorrow." Sonic then said to him.

Slowly walking away, Sonic then left Tails' room and headed outside. This was why Tails was locking himself up in his house not trying or forcing himself to see anyone to try calming down or even helping him, because he was just too depressed about what he did even if it took longer than 3 weeks to get over.

"That was odd. I can't believe this. I never thought Tails would be like this and not tell me and now he's not even letting me help. I'll talk to him first thing in the morning just to let him calm down a bit, if it actually helps."

Then Sonic ran back home. Tails was looking out the window watching Sonic run back home then returned to the flower pot that was sitting on the bedside table. He couldn't let this go. He also didn't want to shoot Cosmo when trying to save the galaxy but it she wanted the galaxy to be safe just like she wanted it too. The seed that was in the flower pot was all Sonic brought to him when he was searching for her but nothing else was left of her. Tails wanted the seed to grow and it was only growing a tiny bit.

"Why did you have to go Cosmo? I didn't want to shoot but you made and convinced me to do so. I know it was what you wanted but I didn't want to let you go. We could've had a happy life together with everyone else. I just wish Sonic didn't bring up the idea to use the Sonic Power Cannon but it was our only chance to defeat the Metarex. I'm so sorry Cosmo."

Tails started crying harder. Nothing right now like rethinking the event from the battle, telling himself that he was sorry and getting a visit from Sonic wasn't helping. He didn't mean to snap at Sonic from earlier as well but this was getting too much to cope at this very second.

Life was very hard for him now. He had no use to invent anything anymore because he thinks his inventions were now deadly. All of his inventions were great and it didn't mean any harm to Sonic and the others, well except when it's something to defeat Eggman with, but right now, Tails was thinking the hard way with it. Besides, he had nothing to create because his mind wasn't in thinking mode. Eggman wasn't attacking at all for some reason so there was no use to get him to force himself to create anything to fight back with. There was no sign of explosions outside or far away, no messages/letters from Eggman explaining his latest scheme, or even to citizens screaming for help. Tails was glad to have peace for a while but it still haunts him when he was up in space far away from home and losing the one who he cared about so much. Now there was no hope at all. Tails had enough of this so he said goodnight to Cosmo's seed, turned his lamp off and drifted off to sleep, hoping that the reoccurring nightmare didn't cause him anymore nightmares and make it a sound sleeping night.
