funny story: this scene was actually improvised. the script originally called for pikachu to roll over onto his side and deliver a line that went “good battling today ash. can we get ihop in the morning?” but during filming, pikachu started thinking about how his real life trainer never hugged him and also will smith’s dad, so he delivered this amazing performance all off the top of his head. the animator was like whoa wtf. what a brilliant moment.
Presently it grew altogether dark: the air itself seemed black and heavy to breathe. When lights appeared Sam rubbed his eyes: he thought his head was going queer. He first saw one with the corner of his left eye, a wisp of pale sheen that faded away; but others appeared soon after: some like dimly shining smoke, some like misty flames flickering slowly above unseen candles; here and there they twisted like ghostly sheets unfurled by hidden hands. But neither of his companions spoke a word.
At last Sam could bear it no longer. “What’s all this, Gollum?” he said in a whisper. “These lights? They’re all round us now. Are we trapped? Who are they?”
Gollum looked up. A dark water was before him, and he was crawling on the ground, this way and that, doubtful of the way. “Yes, they are all round us,” he whispered. “The tricksy lights. Candles of corpses, yes, yes. Don’t you heed them! Don’t look! Don’t follow them! Where’s the master?”
Sam looked back and found that Frodo had lagged again. He could not see him. He went some paces back into the darkness, not daring to move far, or to call in more than a hoarse whisper. Suddenly he stumbled against Frodo, who was standing lost in thought, looking at the pale lights. His hands hung stiff at his sides; water and slime were dripping from them.
Then Fingon looked towards Thangorodrim, and there was a dark cloud about it, and a black smoke went up; and he knew that the wrath of Morgoth was aroused, and that their challenge was accepted. A shadow of doubt fell upon Fingon’s heart; and he looked eastwards, seeking if he might see with elven-sight the dust of Anfauglith rising beneath the hosts of Maedhros. He knew not that Maedhros was hindered in his setting forth by the guile of Uldor the accursed, who deceived him with false warnings of assault from Angband.
But now a cry went up, passing up the wind from the south from vale to vale, and Elves and Men lifted their voices in wonder and joy. For unsummoned and unlooked for Turgon had opened the leaguer of Gondolin, and was come with an army ten thousand strong, with bright mail and long swords and spears like a forest. Then when Fingon heard afar the great trumpet of Turgon his brother, the shadow passed and his heart was uplifted, and he shouted aloud: Utúlie’n aurë! Aiya Eldalië ar Atanatári, utúlie’n aurë! The day has come! Behold, people of the Eldar and Fathers of Men, the day has come! And all those who heard his great voice echo in the hills answered crying: Auta i lómë! The night is passing!
