             Some parts of the story is going to be told the same as the beginning so you can understand better. Continue please and I hope you enjoy.

          Sirius black and Nellie Jerome were at it again. Those two 11 year olds would argue in front of the queen and not care.
        "Sirius, you are going first, I've got to keep my eye on you, you know I don't trust you, you git." Nellie yelled at him as Nellie's mum groaned along with Sirius'.
       "No Nellivra, you are going first, I must keep my eye on you, I definitely don't trust you." Sirius yelled straight back at her.
       "Just go together for my ear drums sake!" Nellie's Mum, Jennifer Jerome, yelled at the both of them. They sighed and went together.
       "1...2...3!" they yelled and ran with each other. They did what Nellie's mum said in order to not get into that mess.
        "Now remember, get into Slytherin. Think hard that that is where you want to be. You come from a long line of slytherins and you are not going to be the one breaking that tradition." The mother's said together. They couldn't stand the thought that was crossing through their minds. 'This child is going to be in Gryffindor'.
         "Yes Mother." the two children said, perfectly in sync, with mocking voices as they traveled onto the train. The other was never once leaving their sight. Since they refused to not be able to keep an eye on each other they were forced to share a compartment.
         "Now you stay seated right there." Sirius stated in a warning tone as Nellie glared.
         "Only if you stay right there." She shot back at Sirius as they sighed and watched each other like hawks. Suddenly the compartment door flung open revealing a boy with glasses.
         "May I sit here?" The boy asked as he was watched by the two.
        "Sure!" They replied and then glared at each other.
         "I'm Nellie/Sirius and you are?" they said in unison and then they face each other after looking at the boy.
          "I wanted to introduce myself first!" they said together. They were already used to the talking in unison and it was no use to argue about the stolen words.
          "Well too bad." they bit back as the boy stared in wonder.
           "I'm James Potter, are you two twins." James asked as he thought that they must be.
          "Where the bloody hell would you get that idea?" they asked James as they went straight back to the watching each others every movement.
          "Well, the fact that since I've met you both, you've only talked in unison kinda gave me that thought." James said smirking as the two stared at him bewildered.
          "Me related to that thing? You're absolutely bonkers!" Nellie gasped.
          "I mean, how could you ever associate us as related?" Sirius said next.
          "That is a mad idea, I'm too beautiful." she said.
          "Do you think I could ever be related to that mirror breaker?" Sirius gasped at the idea.
          "I mean, even his reflection walked away, and his brain went with it!" Nellie stated in horror.
         "I wouldn't trust her with a penny!" Sirius gasped in fake pain.
          "If you don't like each other then why sit together?" James asked confused.
         "I can't trust that git, I have to keep my eye on it." They said talking in unison again. That's when Remus lupin opened the compartment.
        "Can I sit here?" he asked the three strangers.
       "Yes." Sirius and Nellie stated as James nodded.
         "I'm Remus!" Remus stated.
        "I'm James, that's Sirius and Nellie." James sighed. "But know what you're getting into." James stated as Remus sat down.
        "What's that supposed to mean, I am a very pleasant person." Sirius and Nellie stated.
         "No you're not!" "shut it!" "Nellivra/Sirius!" "I thought we agreed silently not to argue like this!" "You started it!" "No!" "That's bloody it!" They yelled tackling each other.
         "Do not ask if their related." James warned Remus.
        "Because we aren't nor will we ever be related, if we do become related I'll shave my head!" The two said. They brushed themselves off as they once again took their seats and stared.
          "What's with the creepy no blinking stare thing?" Remus whispered to James.
          "They don't trust each other and refuse to not keep their eye on the other." James whispered back. Suddenly a prefect came in.
           "Change into your robes, we'll be there soon!" She stated as Sirius and Nellie groaned.
           "Worst part of the day, out James, shoo Remus, we're about to change!" Sirius stated shooing them.
           "We're? as in both of you together?" Remus asked confused.
           "Yes, we've done it before, as you can tell we don't trust each other." Nellie stated as Remus's eyes widened.
          "Aren't you embarrassed?" James asked as they sighed.
          "If we were then we'd have to be embarrassed for taking baths together and using the bathroom together, that baths happened when we were 3 but we still do the bathroom thing." Sirius stated as James and Remus burst into laughter.
         "Bloody Hell you both are close!" Remus said laughing.
          "Closer than best friends, were as close as enemies!" They stated as Remus and James finally left. They quickly changed and unlocked the compartment. A few minutes later Remus knocked on the compartment.
           "ARE YOU BOTH DONE!" James yelled probably alerting the whole train.
           "Yes!" The two yelled as the door burst open and Remus and James found them both in the same exact seats from before.
           "So what house do you want to be in?" James asked as Sirius and Nellie finally agreed on something.
           "Gryffindor, we both come from long lines of slytherins and we both dread having to see our own families almost as much as we dread seeing each other!" Nellie stated as Sirius agreed.
            "Same, I want Gryffindor like my parents!" James yelled.
         "I either want Gryffindor or Ravenclaw." Remus stated. They could all tell they would get along great. Suddenly a red haired girl walked into the compartment with a greasy haired boy.
        "Can you people keep it down please?" She asked as all four heads snapped towards her.
        "But this is our inside voices, it's just a both louder because of that." Sirius and Nellie said pointing at each other.
         "Are you two twins! I'm Lily Evans, I wish I had a twin." Lily said excitedly as James gulped.
       "Just when I thought that they were done." James muttered.
       "How dare you!" Sirius yelled.
       "I'm injured!" Nellie yelled.
      "I will never be related to that!" the two said together. "She breaks mirrors!" Sirius stated
           "His reflection walks away!" Nellie stated.
      "She is unbearable!" Sirius gasped.
       "He is going to be the death of me!" Nellie said in shock.
         "My enemy!" they yelled pointing at each other once more.
         "Then why... " Lily was cut off by James.
        "They don't trust each other, they've decided that they will keep an eye on the other always, they even use the bathroom together." James stated smirking.
         "That makes them close." Lily stated with wide eyes.
         "Closer than best friends! We are as close as enemies." Sirius and Nellie stated with no trace of humor.
