You Can See Who She Was In The Flashback And Part Of What She Could Have Been In Present Ekko - Tumblr Posts

Ekko vs. Jinx was absolutely masterclass, such an immaculate display. The foreshadowing flashback with implication they shaped and mirrored each other in combat/tech ingenuity. Showing the routine reenactment of their formative days, as a means of Ekko reaching out. Brought on one of few comforts in Jinx's shattered memory. Imo, the glimpse they shared in the end signifies Jinx saw that Ekko still cares for her; the Powder within Jinx and possibly even who she became (reason for why her expression was solemn yet wistful as she pulled the pin). As he's all but certainly the only one who can empathize as well as fully comprehend the process that shaped her beyond the deaths of Mylo, Claggor, Benzo, Vander and the loss of Vi (he went through it all the same. Witnessing all the fallout firsthand alongside her). She's just too far gone. Their shared, ill-fated experience made them greater. Yet caused one to break; Jinx. As one harnessed it for the good of those around them; Ekko. Such a poetic tragedy.

That pain that feels like it'll eat you from the inside out, can either break you or forge you into something greater. -Silco
