Darcy in the Lizzie Bennet Diaries

I forget the exact episode of the Lizzie Bennett Diaries that discusses what would presume to be the first instance of Darcy showing interest in Lizzie.  The night of the presumed to be bad dinner party, Lizzie and the gang go out for drinks and arcade games.  From Lizzie's perspective, we learn Darcy was in the corner with Caroline.  From Charlotte and Jane, we learn that Darcy seemed to be focused on Lizzie and did not seem to know how to show his interest in a socially acceptable way.  In the novel, we as the readers do not really see Darcy's interest till he proposes and it seems out of line.  In watching these videos, Darcy comes across as kind of awkward and socially inept, but not necessarily out of line in his behavior.  We see Lizzie's judgment of him first.  My question is, what can we gleam from this series about Darcy and how this speak to the human condition?
