Elizabeth was nervous about meeting Georgiana and seeing Bingley again, to say nothing of Darcy:

"Elizabeth, on her side, had much to do. She wanted to ascertain the feelings of each of her visitors; she wanted to compose her own, and to make herself agreeable to all; and in the latter object, where she feared most to fail, she was most sure of success, for those to whom she endeavoured to give pleasure were prepossessed in her favour. Bingley was ready, Georgiana was eager, and Darcy determined, to be pleased. " (ch 44)
