It’s a new Merlin episode this week and it’s Arthur’s birthday. In The Wicked Day, the town is celebrating with dancers, jugglers and acrobats to entertain the prince but he’s not easily impressed. Back in the staging area, we see two circus jugglers discuss their recent delivery of knives which suggests that it might be used for more than just entertainment. Tune in this Friday to see if an assassin’s attack on Arthur’s birthday casts the kingdom into chaos. (Syfy)

Watch this sneak peek and tune in Friday night at 10/9c, on Syfy.
