I definitely think that the three lieutenants are representatives of the dead three at this point. I'll also just say that I'm less than thrilled that the female lieutenant is just the "scantily clad sexy psycho" trope. Very original Larian. Bravo.
I wondered why she didn't get a spotlight moment all to herself like the others did... until I saw her. Then I knew Larian wanted to bury her in as quickly as possible. She'll be popular, I'm sure, but I'm guessing Larian didn't want to go through the PR nightmare of explaining the villain's excess sex appeal.
