As unlikely as it may seem that people would spontaneously express themselves in rhyme, that is the intent of all of Shakespeare's rhyming lines (and they occur in most of his plays). There is no suggestion that Juliet (or Romeo for that matter) had learned the lines beforehand. On the contrary, the suggestion is that their passion is so great that it spontaneously expresses itself, not only in rhyme, but in Sonnet form. This is the opposite of a disguise. It is a revelation.

Romeo does not recite a poem to Juliet. When they first speak to each other, their dialogue forms a poem, but they are not reciting, just talking.

The fact that Romeo and Juliet write poetry together, off the cuff, in the way they talk to each other not only reinforces that they have fallen in love at first sight but also establishes them as star-crossed. They are immediately on the same wavelength, because they were meant to be together.

Juliet is initially frightened when Romeo joins her in the balcony because she is surprised and fearful of being caught by others. She is also afraid of the words Romeo overheard her speak because she had just revealed her feelings for him, and she is unsure of how he will react or if he will reciprocate her love.
