"Now, gods, stand up for bastards!" (Shakespeare I. II.)
Cordelia notices they are lying, and that she simply cannot do so as well. In turn she tells him the truth, that she really does love him. But only as much as logically possible.

King Lear is furious, however Kent tries to step in and defend Cordelia...
