Lysander, keep thy Hermia. I will none.
If e’er I loved her, all that love is gone.
My heart to her but as guest-wise sojourned,
And now to Helen is it home returned,
There to remain.

– William Shakespeare

A Midsummer Night’s Dream, Act 3, Scene 2. Demetrius, after his enchantment by the fairies and under the influence of Puck’s magic, declares his love for Helena – once again! He first loved Helena. Then he loved Hermia and couldn’t stand the sight of Helena. Now he suddenly discovers that it was Helena all along. Demetrius, thy name is fickleness. This passage uses a metaphor to describe how Demetrius’ heart visited Hermia while on a small journey, but now it had returned home to Helena and would remain there.
