Tell him I must see him again--must speak to him instantly.-- I cannot rest--I shall not have a moment's peace till this is explained--some dreadful misapprehension or other.-- Oh go to him this moment." "How can that be done?
No, my dearest Marianne, you must wait.

This is not the place for explanations.

Wait only till tomorrow." With difficulty however could she prevent her from following him herself; and to persuade her to check her agitation, to wait, at least, with the appearance of composure, till she might speak to him with more privacy and more effect, was impossible; for Marianne continued incessantly to give way in a low voice to the misery of her feelings, by exclamations of wretchedness.

In a short time Elinor saw Willoughby quit the room by the door towards the staircase, and telling Marianne that he was gone, urged the impossibility of speaking to him again that evening, as a fresh argument for her to be calm.

She instantly begged her sister would entreat Lady Middleton to take them home, as she was too miserable to stay a minute longer.
Lady Middleton, though in the middle of a rubber, on being informed that Marianne was unwell, was too polite to object for a moment to her wish of going away, and making over her cards to a friend, they departed as soon the carriage could be found.
