What is the scope of rebuttal evidence in a civil case?

People v. Loker (2008) 44 Cal.4th 691, 709, 80 Cal.Rptr.3d 630, 188 P.3d 580 ( Loker ).) "The scope of proper rebuttal is determined by the breadth and generality of the direct evidence. If the testimony is not limited to any singular incident, personality trait, or aspect of [the defendants] background, but paint[s] an overall picture of an honest, intelligent, well-behaved, and sociable person incompatible with a violent or antisocial character, rebuttal evidence of similarly broad scope is warranted."
