The word 'excitement' occurs twice in the corpus. On both occasions it is verse-initial, in the plural, and introduces a phrase of similar syntactic and prosodic shape.
Ham.4.1.58 Excitements of my reason and my blood,
Tro.1.3.182 Excitements to the field, or speech for truce,
The word-forms 'plot' or 'plots' occur within five lines in Hamlet and and within two lines in Troilus. 'Plot' occurs 77x in Shakespeare, about once every 10,000 words or twice in three plays. Thus the collocation of 'plot' and 'excitement' exceeds expectation, though it may be well be an accident.
