This quote in the book relates back to the theme of love. When Orlando begins to doubt her marriage we can see that the bond between her and Shelmerdine is beginning to weaken. Orlando rethinks her marriage by asking questions she thinks will make her marriage invalid. This is an interesting part of the novel because Orlando was so quick to marry Shelmerdine, however after time elapsed she begins to have her doubts.

This quote is an example of metaphor. Antonio compares Sebastian and Viola to an apple cleft to demonstrate how they are twins.This comparison enhances Antonio's argument that the Sebastian and Olivia are related because Sebastian can not split himself in half.
