Sirius stood up from the armchair and went to open the door.
"That's probably Minerva." he said cheerfully. "You'll have to wait for your coffee, Harry, Ron."
"Its fine." said Harry, Ron nodding emphatically. Sirius opened the door.
"Minerva, how-" he began but stopped when he saw who it was. A woman, in her early twenties, was standing on the doorstep, with a rucksack on her back. She had short, messy black hair and stormy grey eyes identical to Sirius'. Sirius was stunned.
"A-Alex?" he managed to say.
"No, its Mother, back from the dead." replied the woman irritably, pushing past him into the house. "Of course it's me Sirius, who else would it be?" Sirius followed her in, staring at her in wonder.
"Never thought I'd see the day that my little sister Alexandria came back. Where have you been?"
"Places." she replied, leaving her rucksack by the door and walking straight into the living room. Sirius headed after her quickly, not wanting a confrontation.
"Well, well, well, if it isn't the Golden Trio and their top fangirl." sneered Alex. "Sirius, please tell me he isn't actually your godson."
"Fuck." swore Alex, taking Sirius' seat.
"Anyway, where did you go Alex?"
"Remus sent me to one of his friends in Scandinavia. I went to Durmstrang. After that, I went backpacking in Africa. Then the war started, whilst I was in South Africa, and I helped out there. Eventually, I made my way back here. Oh, and Sirius, I need to tell you something. In private."
"Yeah, whatever." Alex followed Sirius into the kitchen and leaned against a counter.
"Alright, so Sirius. It turns out that Lily and James Potter are alive. Oh, and so is Regulus."
A/N: I know it was short. It is just an idea, I'd appreciate it if you could tell me what you think.
