Are there any dramatic techniques in Act 2, scene 2, of Romeo and Juliet that conveys a theme other than love?

Juliet is somewhat concerned that things are moving too quickly.  She cautions Romeo against swearing his love to her.  She says, "At lovers' perjuries, / They say, Jove laughs.  O gentle Romeo, / If thou dost love, pronounce it faithfully" (2.2.97-99).  She employs an allusion to refer to Jove, the most powerful Roman god, who laughs, she says, when lovers lie to one another.  She's nervous about any deceitfulness on Romeo's part.  The theme of...

Juliet is somewhat concerned that things are moving too quickly.  She cautions Romeo against swearing his love to her.  She says, "At lovers' perjuries, / They say, Jove laughs.  O gentle Romeo, / If thou dost love, pronounce it faithfully" (2.2.97-99).  She employs an allusion to refer to Jove, the most powerful Roman god, who laughs, she says, when lovers lie to one another.  She's nervous about any deceitfulness on Romeo's part.  The theme of deceitfulness is shown as the lovers proceed to marry, bed, and correspond in secret and when Juliet ultimately fakes her own death.

Then, as Romeo and Juliet are preparing to part, she says, "I would have thee gone, / And yet no farther than a wanton's bird, / That lets it hop a little from his hand, / Like a poor prisoner in his twisted gyves, / And with a silken thread plucks it back again, / So loving-jealous of his liberty" (2.2.190-195).  Thus, Juliet means that she wants to keep Romeo close and compares him to a bird who is not at liberty to go far, just like a prisoner who is chained by the feet.  She would keep him close because she loves him and wants him to be near her.  He says that he wishes he could be her bird, and she says, "Sweet, so would I. / Yet I should kill thee with much cherishing" (2.2.197-198).  In this way, Juliet references two themes: freedom (or one's lack thereof) as well as death.  Romeo and Juliet lack the freedom to be together openly because they are also chained by their parents' feud.  With her final comment, Juliet even unknowingly foreshadows the fact that her love for Romeo will lead to his death.
