I believe the scene you're talking about occurs after Ash unknowingly flattens the "I'll cut your gizzard out!" deadite. He then jumps into the scene you're talking about and says "Come to papa!" - in the beginning of this shot, in the background, you see a deadite holding a severed head. After Ash's "papa" line, it cuts to Evil Ash who says "Get him!" - then it cuts to a closer shot of the deadite holding the severed head.
