[1] Academic consensus suggests that Shakespeare named the character Innogen, and the spelling "Imogen" is an error which arose when the manuscripts were first committed to print.
When he fails, Iachimo hides in her bedchamber and uncovers her body while she sleeps, observing details of a mole on her breast which he then describes to Posthumus as proof that he had slept with her.
Taking a drug, she falls into a coma and is presumed dead by the family, who cover her body and sing a song over her.
When she wakes she finds the headless body of Cloten, a brutish character who had planned to rape her while wearing Posthumus's clothes, but had been killed in a fight with one of the men who took her in.
She is reunited with Posthumus, and her father (King Cymbeline), and discovers two of the men who took her in are actually her long lost brothers.
She continually questions both Iachimo and Postumus at the end, refusing to forgive them before finally saying that she will "go home and make the best of it, as other women must".
