Bones doesn't want Booth to let her go. -------------------------------------------------------------------------------------------------------------------------------------- "Booth, don't let me go." Bones says to Booth who is looking down to where Bones is lying on his chest. He looks into her eyes and sees the fear in them. "I won't, Bones, I promise I won't ever let you go." Booth vows. He vowed to never let her go and he doesn't break a vow, especially not a vow he made to her.
