Spoilers - a glimpse inside a scene from "Bury Your Dead".
Gibbs' stomach turns as Abby unpacks evidence from the scene. She's rambling and he can barely stand it. He'd do anything for her so he listens, though it's like a knife twisting in his belly. The litany tells him she's holding onto hope where there is none.
Her words ring with denial but Abby's manic movements betray her devastation. He'd give anything if she weren't the one examining these charred pieces of evidence.
She freezes, looking down as the reality of the evidence in front of her outweighs hope.
"Tell me it's not him, Gibbs."
Abby whirls to face him, her eyes shining with tears she refuses to let fall. She launches herself into his arms pleading again, "Tell me it's not him."
He'd give anything to tell her that, but it's a lie. Tony is dead.
He chokes down his despair and manages a hoarse whisper.
"I wish I could, Abby."
