JMO. KC is devoid of emotion, therefore, will not show any. Devoid of the ability to empathize with others, therefore, she will not. KC mimics others as she has no feeelings of her own and in a courtroom there will be no one to mimic as it is rare for emotions to come out on the table in a courtroom. The only people to mimic will be the very stoic attorneys. That is what KC will be stoic. Stoic as stone....until they start talking about KC then one might see her face brighten, a smile or at least a grin, her attorneys will try to stifle but it will be there for all to see. Then the sentencing face, we may, if justice prevails for Caylee, see tears as the Judge announces sentencing and KC cries for KC's own life. That in MHO is the only true emotion we will see from KC is her concern for herself.
