Sira's pov
I was released from the hospital wing quickly since I wasn't injured and I reunite with error, who says he may have found John somewhere in the muggle world. After the house cup was handed to Gryffindor and harry packed up to leave I ask him," mind if I come with you? I can shrink myself down and I can survive off practically nothing, besides, your wizards can't track my magic, so if you ever need just a bit of protection." He nods," yes, I was actually gonna ask you that stuff." I smile and harry says," besides it gives you a chance to look for your brother right?" I nod," yeah I guess it does."
Later

We all board the train once again and speed off toward the muggle world. After several hours of fun I shrink down and fit myself into Harrys pocket as he takes out his trunk and owl to the small car that his adoptive family had.

A month later

Not much has happened since we arrived at little whinging, the search for john has gotten nowhere and I wasn't getting any updates from error by terror mail. It worried me cause error might have to result to portal messaging, but since he had no idea where Harrys house was it was kind of hard to do that form of messaging. I sigh and I stand on Harrys bed. He was currently downstairs having breakfast before some event tonight. He would sneak me a bit of food from breakfast and then I could get back to searching the muggle world. So far the search was going horribly, i was just hoping that error would pick him up from hogwarts.
Later that night my ears perk up at a feeling of wizard magic and I turn to see a strange elf looking creature. I draw my blade and i take off, flying up to the creature." Who and what are you?" The creature responded," I am Dobby the house elf" i slowly let my body expand and grow, showing off my full height." What are you doing here at Harry Potters place?" Dobby sits down and he thinks before saying," to warn him to not go back to school" i ponder that for a minute before i sit and ask," why? Thats both of our home" " something big is happening this year by my -" he suddenly leaps up and starts smacking himself with a lamp. Instictivly my magic flares and calming white magic goes into him and he stops and i focus, just trying to keep him calm before asking," what will be happening at hogwarts? And trust me, i'll pass along the message" dobby thinks and i add," none of your rules apply to me, i want to know, so that i can protect harry. He isn't safe here in the muggle world, which is why i'm here." He smiles and sighs in relief," good, then you can protect him from the darkness coming, i can't say any more, unless i seriously want to be punished when i return, just please, protect him." He snaps his fingers and dissapears, a pile of letters and scrolls sitting there. I check one of the scrolls and i see errors erratic handwriting and i open it and slowly start to read, feeling errors panic through the words but it looks like john found his way to hogwarts on the lake. I sigh in relief and i grab my terror and i write a message saying," i'm fine, a Houself decided to clog up the mailing, i'm glad john is safe." Before rolling it up and wrapping it around the terrors leg and i have it take off. I shrink back down and i put the scrolls in my bag to read later and harry comes in and i tell him what happened. Suddenly downstairs is in an uproar and harry grabs me and hides me in my bag under the bed and says" hide, stay here" i nod as he gets up and the door slams open. The man named Vernon yells at harry that somehow his magic carried a cake from the kitchen to the livingroom and dropped on one of the guests heads. The houseelf. He continues to yell before giving out his punishment the next morning by locking the window with large metal bars and old memories surface as i look out the window and grow myself to full size, my old memories pulling at me. Harry notices my distress and he grabs my arms," are you ok?" I shake my head," my memories are a dark horror that i wish on no one. Alot of my life was behind bars. I was hoping to help, but i had no chance to help, and now we're locked from where we belong." Harry softly says," we'll get back, the matter is just how. It's unlikely your terror will get back to error in time. The door is only unlocked for bathroom breaks." I sigh," we need help to do it, i could try to at least go find some help, other then that i can't help." My ears perk up as i hear a strange engine but i couldn't hear it rolling on asphalt. Sure enough my bright eyes catch a flying car." Harry look, a flying car" Harry perks up and comes to the window and he sees the car pull up alongside the bars," hullo harry, Sira, we've come to pick you up." Ron says, smirking from the back seat and fred says," error sent a message via portal that he believed you both were in trouble, so we figured we'd come drop by to help" i giggle," man i can't be happier that Error is so protective of me, let me help you get these bars off." I take off, growing to my normal size and we wrap a rope around the bars tightly and i grab it, pulling it taunt and dark magic flows down my arms, strengthing my pull and we rip it out. The bars fall onto the hedge below and we load harrys stuff into the car when i heard the dursleys coming." Harry! Grab on!" I reach out my hands and he leaps, vernon grabbing his foot as i grab his arms and i flap my wings harder, blowing vernon with gusts of wind, distracting him enough to get him to let go and it blows him safely into the room. We take off, flying for who knows where.
