The sun was nearly close to setting, and Dwarves and Scoobies were running out of time. Knowing that the hidden door was somewhere on top, Bilbo followed the Dwarves and Scoobies as they all painstakingly make their way up the steep and treacherous steps and find a little rock-walled clearing in the side of the mountain. Thórin runs to the clearing first and makes a sudden stop to read the map.

"This must be it." Thórin whispered. "The hidden door." He turns to face the Dwarves and Scoobies who come into the clearing as well. "Let all those who doubted us... rue this day!" He cheered as the others cheer as well.

"Right. We have our key." Dwálin said.

"So now that we got the key, which means there is a keyhole which I don't see." Spike responded.

"We haven't come all this way for nothing." Buffy said.

Thórin begins exploring the walls of the clearing with his fingers, looking for a keyhole. He walks to the edge of the clearing and looks out at the setting sun. "The last light of Durin's Day will shine upon the keyhole." He read the words as he looks at the wall and tries to figure out what the light hitting the wall means. As the sun gets lower and lower on the horizon and nothing changes on the wall, Thórin started to get frantic and whispered to Nóri. "Nóri."

Nóri runs to the wall and begins tapping it in different places with a spoon while holding his ear to a cup held against the wall. As the sun was getting lower, Dwálin strains and pushes against the wall.

"Ah guys, we're losing the light." Harmony informed loudly.

"Come on!" Dwálin yelled as he kicked at the wall.

"Where is the bloody keyhole?" Spike growled as he begins to kick the wall with his foot.

"Be quiet! I can't hear when you're both thumping." Nóri cried.

"I can't find it... it's not here!" Spike yelled. "It's not here!"

As the sun gets closer to disappearing, Thórin frantically gestures to the other dwarves.

"Break it down!" Thórin shouted.

Immediately, Dwálin, Bifur, and Glóin smash at the wall with their weapons, but there was no avail.

"Come on!" Thórin shouted frantically.

"Guys, there's no point of all this!" Buffy shouted.

"Just give up!" Tor exclaimed.

"Keep up!" Thórin shouted.

"It's no good!" Bálin claimed. "The door's sealed."

"Bálin's right." Anya agreed. "It can't be opened by force."

Dwálin, Bifur, and Glóin drop their weapons in tiredness and disgrace as the sun disappears behind the distant mountains.

"The light's gone." Riley whispered and a slight sigh.

"It can't be." Buffy whispered as she shook her head.

"How is this possible?" Rhonda asked, looking confused as she turned to Xander. "You told us that last light would shine at the keyhole."

"Maybe it was the wrong spot." Faith guessed and turned her eyes directly at Thórin. "Thórin?"

"No." Thórin whispered in shock and stumbles forward and re-examines the old map, reading aloud. "The last light of Durin's Day will shine upon the keyhole. That's what it says." He holds his arms open is disbelief. "What did we miss?" He then walks up to Bálin, and repeats his question tearfully. "What did we miss, Bálin?"

"We've lost the light." Bálin replied softly. "There's no more to be done."

"We had but one chance and it failed." Xander sighed.

"Then I guess we came all the way here for nothing." Faith said and gets ready to leave. "I'm done with this."

"Me too, I quit." Kyle said and turns away.

"Me three." Spike said, raising his hand and walks pass Buffy. "See you down blonde."

The dwarves bow their heads in despair and turn back toward the stairs. The rest of the Scoobies began to do the same thing.

Buffy walks over to Thórin and whispered. "It's over, Thórin. Just let it go." She turns to walk away.

"Wait a minute!" Bilbo exclaimed confusedly. "Where are they going? You can't give up now!"

"Bilbo, it's over." Buffy said calmly to him. "There's nothing we can do."

Bilbo looks beseechingly at Buffy as she walks away. He stared at Thórin, but the dwarf turns away. He holds up his key and looks at it for one moment until he drops it to the ground. Then, Thórin throws the map at Bilbo's chest and walks past him. The dwarves begin descending down the stairs, but Bilbo stays in the clearing.

"Stand by the grey stone..." Bilbo recited the riddle from the map to himself while gesturing with his hands. Then, he goes to stand by the grey wall. "When the thrush knocks..." He looks around but doesn't see a thrush anywhere. "The setting sun... and the last light of Durin's Day will shine. Hmm. The last light. Last light…" He turns away from the wall, thinking hard and muttering to himself. With a thought, he looks up and sees the clouds move aside to reveal the moon. He looks at it wonderingly and sees that it illuminates the clearing. Hearing a noise, he turns back and sees a thrush hitting a snail against the grey wall. Just then, the moonlight hits the wall.

As the thrush flies away, Bilbo laughs with relief and delight and points at the wall. "The last light!"

The moonlight illuminates a keyhole in the rock, and Bilbo gasps in surprise. "The Keyhole!" He called for the Dwarves and Scoobies. He peers over the edge of the clearing at the stairs, but sees no sign of them. "Come back! Come back! It's the light of the moon, the last moon of autumn! Ha ha ha!" He then begins looking around on the ground. "Where's the- Where's the key? Where's the- it was here…but it was here, it was here! It was just…"

Bilbo is looking frantically around on the ground in the clearing for the key, suddenly, his foot hits it and it goes flying from the clearing. Just before it falls off the side of the mountain, a boot steps on the string and stops it. It was Angel. Angel slowly reaches down and picks up the key, then examines it. He turns around and passes the key to Thórin. The Dwarves and Scoobies smile in relief, and they all watch as Thórin inserts the key into the keyhole and turns it. He pushes the wall, and an unseen door opens into the mountain. The seams of the door. The door opens into a tunnel going into the mountain and the Dwarves abd Scoobies look in awe.

"Beautiful." Cordelia whispered in awe.

"Erebor." Thórin whispered with a smile.

"Thórin..." Bálin chokes up, and Thórin puts a hand on his shoulder.

Thórin then steps into the mountain and begins to remember what it was like in the past. "I know these walls." He whispered as he looked around. "These walls, this stone. You remember it, Balin. Chambers filled with golden light."

"I remember." Bálin nodded his head as he steps into the tunnel.

The rest of the Dwarves and Scoobies slowly and reverently enters the mountain. Inside, Nóri points at a carving in the wall above the door; it is of the throne of Erebor, with the Arkenstone above it, sending out rays of light in all directions.

"Herein lies the seventh kingdom of Durin's Folk." Glóin read aloud of the inscription on the carving. "May the heart of the mountain unite all dwarves in defense of this home."

Bilbo looks at the carving in interest and curiosity. Bálin explains it to him.]

"The throne of the king." Bálin explains it to him.

"And what's that above it?" Cordelia asked.

"The Arkenstone." Balin answered.

"Arkenstone… and what's that?" Bilbo asked as well.

"That, Master Burglar, is why you are here." Thórin responded.
