Arcane: League of Legends (2021) - S01E03 - The Base Violence Necessary for Change

Years ago, Silco and Vander fought together to free the undercity from Piltover. This changed when Vander betrayed Silco and tried to drown him in Zaun's toxic river. In the present day, Vander stops Vi from turning herself in. Silco then captures him while the mutated Deckard kills Grayson and her men, sparing only Marcus. Vi, Mylo, and Claggor go rescue Vander. In Piltover, Jayce and Viktor secretly work with the crystals under the discretion of councilor Mel Medarda and invent Hextech, a new arcane technology. Back in the undercity, the siblings reach Vander but are cut off by Silco. Vi fights off Silco's thugs, but is badly beaten by Deckard. Powder, attempting to save her, detonates one of the crystals in an explosion that kills Claggor and Mylo. Vander, fatally wounded by Silco, injects himself with Shimmer, kills Deckard and saves Vi before dying. In her grief, Vi hits Powder, calls her a "jinx" and walks away. She sees Silco approach and attempts to return to her sister but is ambushed and captured by Marcus. Believing Vi has abandoned her, Powder breaks down in Silco's arms. He embraces Powder and tells her that "We'll show them all."
