Mr. Darcy! I can sense not only his joy, but also his relief in this one little passionate phrase---Elizabeth was his own, at last! How long has he been dreaming of this day!

I wonder why JA did not tell us how Lizzy would call him! I believe there have been lots of discussions in the P&P board about this, but I think she will call him 'Darcy'. My theory is that- Jane speaks of Mr. Bingley as 'Bingley', and even Lydia addresses her husband(snort!), as 'Dear Wickham'!
