It may be the perpetual "Pollyanna" in me, but even though I'm sure Martinez fought valiantly to keep this drivel out of the trial, he has had warning for quite a while that this might happen.
I imagine him spending lots of time making a detailed outline of his cross examination, including every possible question he would like to ask along with evidence to firm them up.
Will he ask his questions "scattershot" and aimed at the lies, or will he slowly draw JA into her web of lies and trap her in them?
I have far more than a sneaking suspicion that Det. Flores and his staff are doing a lot of digging into records to help in his quest for justice.
Nurmi may try to ambush him, but Martinez thinks way to far ahead for that.
I always get nervous during the defense case. In this one, I am literally sick to my stomach. But, I have to remember that the prosecution always goes last.
ETA: Any time the jury gets lulled into believing the delicate defendant, one quick flash of an autopsy picture should jolt them back to reality.
