The Secret Sharer was a great episode of Merlin and I really enjoyed watching this episode because Agravaine points the finger at Gaius as being the traitor and user of sorcery which almost leads to the discovery of Merlin's true identity. The suspense and action were fun and the drama and intrigue were entertaining. There was some development here, but it was a little bit of just the same old story. It does feel like the series is building up to reveal Merlin's powers to Arthur, but it is taking forever! I look forward to watching the next episode!!!!!
