Not quite, seeing red doesn't happen every time. It depends on the severity of the situation, remember he was hit from behind. A surprise attack gives no opportunity for an adrenal reaction. His brain had no time to process just how screwed he was. Depending on how much time past from the elbow to the back of his head till he grabbed the bat, chances are he was just beginning to feel the adrenalin pumping, then suddenly its not a life or death situation anymore, so he starts calming down then before the first dose of adrenalin is gone mom gets hit. BOOM second dose. When that much adrenalin is in someone anything is possible, Mother lifts car off child, Father carries child out of burning building unaware he is on fire.
