Merlin 5.02: Arthur's Bane Part 2

See my round-up of episode 5.01, Arthur's Bane Part 1

We open with Morgana waking from a bad dream. She's in bed, hair unkempt in her usual Amy Winehouse-esque fashion and fully-dressed with boots on - who does that? I love how my main focus is how she's probably making her bed dirty when she's plotting to kill Arthur at the same time ... must get my priorities straight! Anyway, she seeks comfort from her bad dream and we turn to the other side of the room to see a dragon! Aithusa! The same dragon that Merlin hatched last series or the one before! How on earth did Aithusa escape from the Great Dragon?! What's going on in the world?! If you hadn't already guessed, this is a cause for great concern.

Arthur and Merlin are still with their captors and making their way slowly to Ismere. They know that they can't be delivered into Morgana's hands like a sacrifice, but are biding their time to make their escape. Strangely enough, Mordred seems to be on their side and when they do manage to have the upper hand and make a run for it, he stands by and lets them go. Arthur decides to spare his life, despite having ample opportunity to kill him, much to Merlin's despair.
