[x] Be reassuring.
It's not exactly in your nature to be comforting -- but then again, it's not in your nature to be a tattered leather diary either. Seeing as circumstances are so unkind, you have little choice other than to reassure her, lie through your teeth about the disdain you truly feel. You managed it at Hogwarts. Every day for five years, you managed to charm and swindle and captivate those who would have recoiled if they knew the ruthlessness in your heart. It was maddening, at times, but it wasn't hard.
You did it then. You can do it once more. For the sake of your future glory, you will do what you must.
You close your eyes, fighting against the diary equivalent of a headache, and speak.
"No. I am...not hurt." Your strength drains away from you with your words, but unlike before, it is replenished by the lifeline of emotion that is this girl's attention towards you. It's nothing more than a trickle, as it is now, but it will grow into a stream, a torrent, until it is she who draws her strength from you. All you have to do is keep that fickle attention focused on you. "But...do not pour...ink on me...again. Please. I am...fragile."
I won't. I won't, I promise. Oh dear, are you a very old diary? I wouldn't have -- if I had known -- you must be very cross with me.
Worry. Agitation. Guilt. They drip off these girl's words as they become one with you. And they are quite powerful; this girl may be too conscientious for her own good. But now is not the time. You must allay these fears of hers, if she is to trust you and view you as a source of comfort. The fear may be used...later.
"I am...not cross...with you," you say, wincing at the pauses you must take as you speak. "What a clever...experiment. Do your brothers...often...play such tricks on you?"
Yes. God, yes. Fred and George, mostly, but sometimes Ron, too. It wasn't so bad when Bill and Charlie were around, because they thought I was the 'baby' and didn't want the twins to pick on me so much. But now it's just Ron and Percy, and Percy's too wishy-washy to make anyone listen to him, and Ron thinks Fred and George are just hilarious. 'Ha ha ha, we dyed your hair blue last night, isn't that so funny?' I'd prank them back, but I'm not clever enough. They always catch on before I can do anything.
"And your parents...do nothing...to punish them?" (Of course, these pranks she speaks of hardly seem like anything more than childhood mischief, but it would be odd for her parents to ignore all of it. Perhaps they are negligent?)
Mum punishes them for the worst ones. Dad's not usually around until evening, but sometimes he'll sit them down for a lecture -- which they never listen to. I don't think anything they could do would ever stop them, really. You'd have to snap their wands to even slow them down, and they'd probably be at it again in two days anyway. It's maddening.
"I imagine. How...trying...your family seems."
Trying...?
There's confusion in that word. It seems you may have to dumb down your vocabulary a bit for this girl's benefit.
"Difficult...to handle," you explain, inwardly rolling your eyes. No, you couldn't have ended up in the hands of someone intelligent, could you? That would be too easy. "But you mentioned...others..."
Right! Bill and Charlie. They're graduated now, so they don't live with us anymore. Bill works for Gringotts, and Charlie is a dragon tamer! He's all the way in Albania, so we don't get so see him much. And even though Bill's close, his work keeps him so busy...
She pauses for several seconds.
I really miss them. Both of them. Even if the twins got all their...wildness...from Charlie.
Minor familial woes, to be certain. Many in the world would give anything for a family like this one -- the fondness in her words betrays how close they really are. But what child does not believe their struggles are the center of the universe? You can exploit these mild disagreements as surely as you could exploit true abuse.
"There, there," you say. "I am certain...they think of you...quite often. A pity...they did not teach your other brothers...to be kinder."
I know. It's awful.
"Truly. But...tell me," you continue, "I know the names...of your siblings...but I am missing one...very important name."
Oh? Whose is that?
...the child is clearly not the brightest.
"Your name."
Oh!! I completely forgot I didn't introduce myself. How rude, I'm already complaining about my brothers and you don't even know who I am. I'm so sorry.
"It is...quite alright. No need...for apologies."
My name's Ginny. Ginny Weasley. Don't laugh, I know it's ugly.
Weasley...did you know a Weasely at Hogwarts? The name sounds familiar -- perhaps some Gryffindor you ignored. Hardly a dignified name, to be sure, but not one of the many bloodlines you knew that were tainted with Muggle filth, so not the worst you could have ended up with.
"It is not...ugly. You are...too hard on yourself," you say. "Is it short...for Virginia...or Ginevra?"
Ginevra. I wish it was short for Virginia. That's so much prettier. Ginevra sounds like an incantation to -- I don't know -- pour someone a drink or something. It's silly. And my brothers all got normal names.
"It is...a noble name...for a noble girl," you say, as sincere as you can manage. "Be glad...that your name is...remarkable. Normal names...are bland...and common."
You feel a tiny surge of pride from the girl -- Ginny -- though it quickly dims.
Do you have a name, Mr. Diary? Or Ms. Diary?
[ ] Be honest. Give the girl your Muggle name, as disdainful as it is. She doesn't like her name, you don't like yours -- it's common ground.
[ ] Be half-honest. Give the girl your chosen name: Voldemort. Depending on your other self's deeds, she may have heard of it, so it is a bit risky.
[ ] Say that you do not have a name. Easier to pretend that you're a simple, enchanted diary.
[ ] Lie. Give a false name.
---[ ] Write-in
[ ] Continue talking about her family. It's clear that she has much to say on the matter.
[ ] Ask about the outside world. As 'charming' as this little domestic portrait is, you need to know what's actually going on.
[ ] Ask about another aspect of her life.
[ ] Allow her to question you a bit. Some reciprocity might strengthen this fledgling bond.
[ ] Ask about this 'Harry Potter' character she mentioned. For some reason you cannot place, this name stands out to you.
