Merlin has stopped working and is on his way to his king. Just in the moment as Sir Galahad has left the king's chamber, he arrived. Worried he looks up to Gwen and Arthur.

Suddenly it clangs loudly and the window glass gets broken! One lightning has made his way through the window and has set fire to the king's bed. Immediately flows thick smoke through the room and makes breathing nearly impossible. First flames are already blazing. Merlin grabs a blanket courageously and tries to smother the fire. Together with Arthur, he spreads a blanket over it. They did it, they killed the fire.

Both turn towards Gwen, she coughs. Then she points at the bed. Both men turn back to find out, the fire has burned through the blanket. Horrified Merlin and his king are looking at each other. This is impossible. The fire was killed! Arthur looks around and takes a water-filled jug standing on the large table. With momentum he pours the entire contents on the fire. The flames are dying again. But before they breathe up, they hear a a crackling hiss ... The flames are burning again. Instinctively Arthur makes a step away from the bed. He looks up to Merlin. The young sorcerer raises his hands and speaks the words "Forp fleoge!" [The fires go out.] As his eyes change his colour, the flame dies. And doesn't comes back. Worried he looks up to his friends. "That was magic fire. This storm is not of natural origin. That is why your men can't fight it."

Arthur is stunned. "And now? Can you stop it?" Merlin shakes his head. "To stop all the fires it needs rain! To kill every single fire I would need days.. until then the whole lower town would already burn." Arthur nods. "So we need rain. And we have to find that sorcerer. It is sorcery, isn't it?" Merlin nods. "It is. And I'm sure, we almost know who caused that. Mordred." Arthur looks despaired. "Mordred? Why do you think that?" Merlin makes a step towards the royal couple. "To call a storm like that, you need big powers. And we know that he was here before. Maybe he is back now. Just remember his threats. Please Arthur you have to be careful." Arthur nods. "Fine. First of all, I have to see the fires with my own eyes." He nods towards Merlin and turns towards Gwen. "Gwen, please stay here in the castle. You and Gaius, you have to look after the evacuted peolpe." The queen nods. "Of course." Worried she watches his husband and his servant leaving the room. Then she takes heart and hurries towards the physician's chambers.
