I don’t see Elizabeth flirting with Lucas or Mountie Whatsisname, exactly. I see some glimmerings of interest, maybe, but not flirting. A year after her husband’s death it doesn’t seem that weird for men to be noticing an attractive young widow.
True, If we were going to be strict about the time period, she should still be in black and certainly not attending dances. My beef isn’t the apparent accelerated mourning. It’s that there’s a freaking giant war going on that no one is acknowledging.
