And that was a powerful moment in the court.

Look, we haven't had a, as we say, we keep calling it a Perry Mason moment.

They made an impression.

They will remember that going into the jury room.

And then to know he ended up dead hours later, that is certainly powerful.

I mentioned demeanor.

When we come back, that has been a huge part of this week with the judge and the attorneys, whether or not that is something that can be allowed into evidence.

We're waiting to hear the defense's third brother theory.
