I am still betting Dorian does remember Brona- he knows exactly what he is doing. He is a major trouble maker. I love his character. Also, while V&E are the classic "good" couple to vouch for, remember this show is about monsters and devilish creatures… so not all the core cast are going to be loveable, always.…

yeah I loved this episode too. And I definitely think Dorian recognised Lily/Brona. Also Dorian is able to love both Angelique and the show of it … that's what makes him Dorian (as per the Oscar Wilde book)
