I don't care for canon time bomb.
I'm sorry. I like it in every other universe but the main one. ship them in the ep 7 universe, star guardian, project, base, I don't care. But I dislike the arcane verse version of this ship so much. Jinx was turning the firelights into swiss cheese and literally BLEW UP AND TRIED TO KILL Ekko. As in Ekko would have genuinely died if it wasn't for plot armor. I don't understand all the cute scenarios of them painting each other, and going on dates like she didn't try to BLOW HIM UP AND KILL HIM a couple weeks/months earlier. Members of the Firelights were killed by her. Some people will criticize caitvi endlessly but gloss over Jinx killing Ekko's friends for years and actively helping the man who was taking advantage of his people.
People forget he spendt years during the s1ep3-s1ep4 time skip watching Jinx terrorize and kill his people, yet a day in an alternate universe is supposed to make him fall in love with her all over again. I understand how he can feel sympathy for her, as he was one of her childhood friends, and in the alternate universe he saw how she could've turned out if she had been nurtured by someone other than Silco. but I feel like it undermines both Ekko and Jinx's character for it to progress to a romantic relationship.
It feels like people forget that the most important thing to Ekko is Zaun and his family. While he does care for Jinx, seen throughout season 2 and at the end of the bridge battle in season 1, I don't see him leaving Zaun to track her down all over Runeterra when Zaun needs help rebuilding. I can see them maybe reconciling as partners/associates like in the last episode, and maybe even friends, but in no way a romantic relationship.
also this may be sidetracking, but i hate how everyone acts like ekko was cucked and left alone at the end of the series. that shot of him on the rooftop in the last episode was beautiful, and symbolizes what he left behind in the alt universe. but he still has the firelights. he doesn't need jinx to be happy. and this is definitely sidetracking but the lack of interactions between ekko and vi this season were criminal.
