Whither thou goest, I will go;
Where thou diest, will I die
And there will I be buried:
The Angel do so to me, and more also,
If aught but death part thee and me.

Our souls are knit. We are one person, James.

When Will truly wants something,” said Jem, quietly, “when he feels something — he can break your heart.

Will has always been the brighter burning star, the one to catch attention — but Jem is a steady flame, unwavering and honest. He could make you happy.

Jem cried out with all his remaining strength. You cannot go where I am going! Nor would I want that for you!

I always loved you, Will, whatever you did. And now I need you to do for me what I cannot do for myself. For you to be my eyes when I do not have them. For you to be my hands when I cannot use my own. For you to be my hear when mine is done with beating.
No, said Will wildly. No, no, no. I will not be those things. Your eyes will see, your hands will feel, your hear will continue to beat.
But if not, Will-
If I could tear myself in half, I would-that half of me might remain with you and half follow Tessa-
Half of you would be no good to either of us, said Jem.
