Continuity mistake: Jake is ordered to remove the children (Colleen and Brian) from the courtroom, and escorts them outside. Yet as Dr. Mike resumes her protest to the judge, Jake is suddenly back in his frontal seat as Bailiff.
Plot hole: Worst writing of any episode. Mike is more than familiar (and associated) with public law and certain rights, given her position as a licensed physician, and the factor that she herself, and members of her extended family are lawyers or in knowledge. Yet Ethan is able to trip her up repeatedly during the course of this trial, incl. 'lack of proofs' etc. Whence Mike should have been able to rest her case without worry or thwart.
Plot hole: In any court case, as applies to this, an "objection" would be applied and sustained or overruled in parlance to Ethan's defamations of Mike. Yet is never once is it called by the judge or anyone appointed including Jake (which by his ignorance of the law perhaps applied).
Answer: A Cooper was someone who made various things out of wood including wooden caskets and even barrels.
