The Darkest Hour Part 2 was a superb episode of Merlin and I really enjoyed watching this episode because it was awesome, and had great character and plot development. The actors were at their best and played their roles perfectly. I loved when Gwen spoke her mind about the gates being shut, as well as Merlin and Lancelot doing their part to protect Arthur. It was cool how the spirits of the brooks healed Merlin and I hope to see more interaction with magical entities like this in future episodes. I look forward to watching the next episode!!!!!!!!
