In The First Part of Henry the Fourth, there are 18 scenes.
In The Second Part of Henry the Fourth, there are 19 (plus the Induction).
In The First Part, Hal appears in nine scenes (two with his father, three with Falstaff, four with both, none without either), Henry in six scenes (two without either Hal or Falstaff), and Falstaff in eight (one without either Hal or Henry).
In The Second Part, Hal appears in five scenes (one with his father, two with Falstaff, none with both, and one with neither), Falstaff in eight scenes (SIX without either Hal or Henry), and Henry in just three scenes (two without either Hal or Falstaff).
In The First Part, Henry has 30 speeches, Falstaff has 151 speeches, and Hal has 170 speeches.
In The Second Part, Henry has 34 speeches, Falstaff has 184 speeches, and Hal has 60 speeches.
Not sure what all these numbers mean… but they’re not what I was expecting. I would have figured that Henry would have fewer speeches in the second play, as he’s not there for all of it AND he’s weaker (and though he does appear in only half the amount of scenes in the second play, he has more lines). I would have figured that Hal would have more speeches in the second play, as he’s growing into a royal personage (but not only does he have almost two-thirds FEWER speeches than in the first play, he also appears in nearly 50% fewer scenes). I would have figured that Falstaff would have about the same amount (or a little less) as his influence over the prince would be waning; instead, he appears in the same number of scenes–three-quarters of which are without either of the other two main characters–but with twenty percent more speeches.
Yep, not what I expected.
