Well, Jack's chickens are coming home to roost and his Beverley disguise is revealed to Lydia, Mrs. Malaprop and Sir Anthony (though it is still in effect as far as Acres and Sir Lucius are concerned.) This was a funny and tense scene. I loved all the asides the four of them were constantly making and how he tries to head off Lydia - "Be not surprised, my Lydia, suppress all surprise at present." She can't do it - she is incapable of subtlety. "Heavens! 'tis Beverley!" "Ah! 'tis all over."

But, I don't blame Lydia for being angry - she feels she's been made a fool of and all her romantic notions have fallen down about her ears. I do think that after all his scheming, and knowing his Lydia's disposition as well as he does, that he might have had more patience with her and stayed to work it all out. But then we wouldn't have an Act V, I suppose. ;-)
