(Here's the first one.
I know. She's supposed to die before him, but let pretend she comes back to life ou something and finds out that he is dead (and after a long time to admit it to herself...))

My Lord...
Come accueil again.
toi have not battled in vain.
Don't leave me alone.
Without you, I cannot hold on,
My Lord...

But if it is the way toi want it to be,
If there is nothing to make toi stay,
Then, it seems that I have nothing plus to say.
Though, I'd want toi to come back to me.
Too much, I miss toi already,
My Lord...

I knew not toi could be even colder than toi were.
Without you, I have no will...
Except! Potter, I shall kill!
I have been your closest Death Eater!
Soon, shall I be your avenger!
My Lord...

My Lord!
Come accueil again!
toi have not battled in vain!
Don't leave me alone...
Without you, I cannot hold on,
My Lord...

I toi only knew,
My Lord!
How I l’amour you,
My Lord!
All my tears in our dark
Shall not be enough to bring toi back!

And so, My Lord!
Oh, My Lord!
Shall I avenge you!
Forever bound to you...
My Lord...

(And now, the seconde one.
Something she could say ou sing (aloud ou not ;)) to herself whenever in the time of the films/books (5, 6 ou 7).
(Again, to Voldemort (only not directly))

I know all too well that toi can easily read my mind.
And I'm afraid of what toi could find.
My soul left behind in this cell.
For you, shall I imprison the jour as well!
No plus joy ou fun,
No plus warm ou sun.
Here comes our night!
For you, I must fight
And I wish I will be killed par “Light”.
Then, will toi regret me to be so still,
Revising your final desire, toi will.
And then, it will be...
Only toi and me-
The world as we want it to be!

They are all constantly
Telling me-
That I am wrong.
Still, your arms hold me too strong.
I no longer breathe and so live.
My dark cœur, coeur has but one love.
And yet, this is too much weight.
Still, it gives it even plus strength!
Before we met, it seemed to be made of stone,
Because it was just too alone.

toi are lovingly heartless.
And it has driven me into what's called madness!
Tell me, who am I?
Tell me why!
Why am I involved in something too big for the little that toi probably
Think I may never be?
So many people to hate a nobody like me,
Who loves but one Lord!
And has no god!

Some may say I am in prison with you.
But I know what is true.
The truth is that only in your arms, can I exist.
No need to resist.

Forever waiting for this kiss...
As toi find me in this naive labyrinth of weakness-
And desire that this thought is,
You’d punish me for the “nonsense” of my faith.
Bringing my childish dreams to their death.
I, sharing their pain,
But unable to stop this rain,
Because it is only the reflection of my sorrow
And into forgetting, all dreams have to go.
