What I meant by "In more ways than one" was their eyes, mostly, but I thought I could leave that open for interpretation.

Dark as shadow,

With eyes of blood

Don't call me an angel

I'm anything but.

I wish I was better,

More worthy to live

And could tell her the truth

But could she forgive?

Her brother by blood,

In more ways than one

For whom she's been searching,

Is not one to be loved.

For that I am sorry.

I always will be.

She never will know,

But will be special to me.
