Since a dynamic character is one who undergoes a significant and basic change in personality or outlook, in Act II of Shakespeare's Romeo and Juliet, Romeo certainly undergoes a significant and basic change in his outlook on love. For, previously in the first act, his mood has been morose. He bemoans the loss of his Rosalind, who has choses to enter the nunnery. He speaks in melancholic tones, using oxymorons to communicate:
...O brawling love! O loving hate!
O heavy lightness! Serious vanity!
'Misshapen chaos of well-seeming forms!
Feather of lead, bright smoke, cold fire, sick health!
Still-waking sleep, that is not what it is!
This love feel I, that feel no love in this. (I,i,149-154)
Yet, in the second act, Romeo lightly scales the walls of Juliet's garden: "He jest at scar that never felt a wound" (II,ii,1) As he gazes lovingly at Juliet who appears o the balcony, Romeo's tone is airy, hopeful:
Oh, speak again, bright angel! for thou art
As glorious to this night, being o'er my head,
'As is a winged messenger of Heaven (II,ii,26-28)
When Juliet asks him how he has been able to gain entry to the orchard that has walls "high and hard to climb," Romeo replies lightheartedly,
With love's light wings did I o'erperch these walls,
For stony limits cannot hold love out.
And what love can do, that dares love attempt,
Therefore thy kinsmen are no let to me. (II,ii,66-70)
From gloom to elation, Romeo's spirit has been lifted in love for Juliet. She is all to him; no longer does he ponder his heartbreak by Rosalind. Now, to him, the world is "blessed" whereas before all has been "serious vanity." Indeed, Romeo has undergone much change in feeling and attitude.
