Bones explains to Eli what is going on and tells her that he will show her the way and be there to guide her until she is ready.
Eli feels it is her time now and feels nothing but peace and love. Bones knows that this is part of life so he doesn't feel sad but happy he gets to be there for those who need guidance to the other side.
Eli found peace. Now bones will go help others just like Eli who can't pass over on their own because they are scared, confused, and lonely. He is the friend for those who need one on their journey.
