@Seink I'm pretty sure that Conrad's hand was shaking for a reason similar to (if not exactly) what
saphirekosmos said. Hopefully, the damage isn't permanent.
Thankfully, Leslie has the Salvatores, Conrad, and her surviving uncle, Taryn, on her side. So, she can safely show just how strong she is.
Also, regarding the trial procedures: this is
fiction-land. Realistic standards may or may not hold up. In this case, it seems to be that the author doesn't know much about law or trials. Since it doesn't effect the story too much, just shrug it off as an excess of fiction-land and enjoy the story.
I'm looking forward to future developments!
