Lo, she is one of this confederacy!
Now I perceive they have conjoined all three
To fashion this false sport in spite of me. –
Injurious Hermia, most ungrateful maid,
Have you conspired, have you with these contrived,
To bait me with this foul derision?
Is all the counsel that we two have shared,
The sisters’ vows, the hours that we have spent
When we have chid the hasty-footed time
For parting us? O, is it all forgot?
– William Shakespeare
A Midsummer Night’s Dream, Act 3, Scene 2. Helena accuses her childhood friend Hermia of joining in a conspiracy with Lysander and Demetrius to make her the target of a sick joke and cruel mockery. She calls Hermia an "ungrateful maid." The two men have been enchanted by a love potion to make them fall in love with Helena. But none of them knows that, while the amused audience does – one of the many examples of dramatic irony in the play.
