Arthur tried to rush after the Merlin, but he got again a hit from single tentacles. The pain cut in deep. So deep, that he remained on the ground, fighting to breath, trying to fight against the loss of consciousness. Another tentacle grabbed him but then let go its grip.

"Arthur!" Gwaine's sword flashed in the descending sun when it struck down, letting the Arthur free again.

"Merlin… Merlin…" Arthur wheezed and Gwaine turned to look at the lake and gasped.

"Oh no. You don't mean that…"

Arthur tried to rise. But the wounds were bleeding too much. He collapsed back into a pool of blood. But still he tried.

"We have to, I have to…"

"You can't do anything." Gwaine yelled to him. Sadness swept over him. "We can't do anything."

"No. no. I ... I promised." Arthur whispered in shock. Another tentacle was trying to strike against them, but again Gwaine managed to slash it. He helped Arthur to stand.

"Lancelot! Percival! Where is Heather!"

"Over here!" Lancelot was running toward Heather who seemed to regain slowly in her unconsciousness. "We have to get out of here!"

"But… Merlin…" Arthur tried to fight against Gwaine, but was too weak.

"I'm sorry but we have to think that about later princess." Gwaine snapped and dragged the man with him. He knew that he sounded harsh and cold, but he didn't see any alternatives. He had seen too much, lost too much, and he surely not wanted to lose Merlin too, but he knew that it wouldn't make sense to jump into the lake after him.

"Where is Merlin?" Gwaine heard Heather's asking when they got nearer.

"Its got him." He answered icyly. "Can you help Arthur?" For a moment Heather stared him, like she just wouldn't to believe what she heard. Then she slowly nodded Gwaine lowered Arthur down.

"Do I imagine, or whether the lake is calming down?" Percival asked. The big man stared to the lake. He was covered in blood and green mucus, which was splashed in the tentacles.

"I though so too." Gwaine muttered.

"This is bad." Heather said when she examined Arthur's wounds. "There is tiny spike inside the wound. Arthur, do you hear me?"

"Merlin?" Arthur asked quietly. "I can hear him. Where is he? He is calling me. Merlin?"

Heather put her hand Arthur's forehead and shut her eyes to concentrate. Then her eyes widened.

"Poison."

"What?" Lancelot asked.

"It must have come from that spike." Heather tried to think. She didn't know what kind of poison was a question, but it seemed fast and devastating.

"Merlin…" Arthur murmured and loosed his consciousness.

"Heather?" Lancelot looked a healer who tried to get the spike out of the wound. But it was small and only penetrated deeper.

"I…" Heather raised her head and her desperate appearance told all what was necessary. Lancelot eyes pressed against the ground. A sudden emptiness came over his mind. Arthur, dying in front of him, and Merlin, perhaps already dead.

"It is coming." Percival said suddenly and the last drop of sunlight melted away.

Do you think that the three chapters on this day is enough? Long, short and medium LOL
