How is Act 2 different from Act 1

Act II operates in many ways as a reversal of Act I. We see the characters reduced down to their most basic composition, based on how they process the evidence. Besides being a halfway point in the case, it marks a halfway mark in 8th Juror’s campaign to convince the other jurors of the defendant’s innocence, with a 6-6 vote taken early in the first act. Whereas in Act I, it seems like the impossible task, now they are on even footing, and the momentum is certainly on his side.
