Shadow and Flame

The episode received generally positive reviews, with praise for the performances and visuals but mixed thoughts on other aspects, including the reveal that the Stranger is actually the Wizard Gandalf.

He attempts to escape with Míriel but she refuses to join him, giving him the sword Narsil and sending him to reclaim his lordship in the west of Númenor.

Kemen claims Pelargir as a military outpost for Númenor and demands the Southlanders and Wild Men cut down the forest in exchange for shelter and supplies.

Durin IV sends his army to aid the Elves, allowing Elrond, Gil-galad, Arondir, and other survivors to escape to a valley north of the city.

Elrond and Gil-galad use the Elven rings to heal Galadriel, and the Elves resolve to stand against Sauron's army as it marches across Middle-earth.

[46] Writing for Vulture, Keith Phipps gave the episode three stars out of five and said it was the end of a "pretty good season", with praise for the visuals and production design.

Club graded the episode a "B" and said the series' strength was in its characters and performances, particularly highlighting Vickers, Edwards, Walker, Owen, and Mullan.

He praised the visual effects of the Balrog sequence but wished more of it had been shown, and was critical of the pacing of the season as a whole with some plotlines being rushed and shortcuts taken.

He praised the production values and the work of Brändström and Disenhof, as well as the performances—particularly those of Vickers and Edwards—but criticized the need to focus on so many storylines, especially the season's less interesting ones, and felt some had been rushed while the reveal of the Stranger being Gandalf had taken too long across the series.

[47] Kristian Milsted was nominated for Excellence in Production Design for a One-Hour Fantasy Single-Camera Series at the 2024 Art Directors Guild Awards for his work on this episode.
