The second part of Merlin‘s exciting season 5 premiere airs on Saturday, and now you can watch a scene in which Merlin reunites with the dragon Aithusa.

In the first episode of series 5, we discovered that three years had passed since the events of “The Sword in the Stone,” and Arthur and Guinevere have so far had a peaceful reign as king and queen.

But now, Morgana has once again risen to power, and with new allies she is ready to take on Camelot’s forces. She is searching for Arthur’s Bane, and has captured most of Arthur’s knights.

In the first part of the episode we saw Arthur and Merlin’s trek to rescue them go awry when they got caught in a net and captured by bandits. But luckily (in a manner of speaking), they were saved by the now grown-up Mordred, who will take them to Morgana.

In this sneak peek video for the next episode, we see Merlin meet Aithusa. This was the white dragon which Merlin saw hatch from an egg last year, and who at the end of the season found Morgana in the woods and presumably saved her life.

The dragon is now attacking Merlin, but he manages to calm it down with Dragonlord speak. He also asks, “What happened?” and it seems like maybe Morgana has been mistreating it.

How do you think Arthur, Merlin and the knights are going to get out of their current predicament? Will Aithusa be a help or a hindrance? And what about the weird creature which approached Gwaine in the mines underneath Ismere? Is he Arthur’s Bane, or can he perhaps lead them to where it can be found?
