There is an alleged sequel where Wickham (much more black-hearted than the original, of course,) comes back from the supposed dead (after inadvertently murdering his own son,) to wreak more havoc and Darcy gets snippy when post-birthing-twins-Lizzie isn't in the mood to let his Longbourne anywhere near her Netherfield.

I prefer to think of it as a cracked-out soap opera version of P&P written by underpaid and disgruntled high-school students.
