Penny Dreadful's Season 2 finale, "And They Were Enemies," wrapped up the Evelyn Poole/witch storyline in bloody, blusterous fashion while also successfully spinning out the series somewhat, creating a curious set up for Season 3. Something done better here than back in the Season 1 finale, which also had most of its carnage in the first half and then spent the remaining time showing us our heroes reeling and recoiling in the aftermath.
