He is the first to realize who the newcomer is, and he is almost across the cemetery before anyone else realizes who he's heading towards.

"What the fuck are you doing here, Jason?" His tone is that of a demand, and there is no familiarity in using Gideon's first name.

Gideon's face is faultlessly calm. "I came to say goodbye."

Hotch laughs, mirthless and contemptuous. "Oh, you can say goodbye to him when he's dead, but not when he's alive?"

Gideon flinches like the words are physical blows. "I did what was best for—"

Hotch strikes out; his fist makes contact with the side of Gideon's mouth and a second later his arms are behind his back, one held by Rossi, one by Morgan.

"Best for him?" He tears his arms from their grips but simply stands there, staring at Gideon with the brightness of tears standing in his eyes. "You fucking left him! You left us!"

He stops himself and stares at Gideon, as everyone stares at Gideon: his words hang stagnant in the air, irrevocable, irretrievable, and he turns and strides away.

A tear-shaped drop of blood slips from the corner of Gideon's mouth, and he bows his head.
