With Sonnet 113, William Shakespeare returns once more to the theme of separation, reflecting on how, when he is away from his younger lover, everything he sees takes on his lover's shape and thus reminds him of him. Although we don't know when exactly the sonnet was written and therefore where precisely in the collection it belongs, it would appear to also, therefore, pick up on the notion, emphatically expressed in the previous sonnet, of his lover being his 'all the world', and it certainly also connects strongly to the sonnet that follows, which will further elaborate on the idea that the younger man with his beauty turns even the ugliest appearance to loveliness in Shakespeare's mind.
