Bro every time I think abt how Karl consistently falls in love with every version of Sapnap he meets but doesn't for Quackity I get so sad... like I know on a meta level it's cuz Q just loves making his characters fucking absurd but on a narrative level. HOOO
Something abt Karl and Sapnap's bond being something cosmic and immortal. While Quackity's and Karl's was something more simple, more human. Sapnap and Karl being guided to each other by the stars while Quackity and Karl found each other by chance and built something all on their own.
Something abt how Sapnap and Karl's connection will persist in every reality, every timeline, while Quackity's was one made entirely unique, by a single set of circumstances to bring two people so close together by chance. Their love being no less real than Karl and Sapnap's, the only difference being that while Karl and Sap's love was for whatever reason intended by the powers that be, his and Quackity's was only determined by their own will, their own want to be with each other.
Something abt the inherent tragedy of falling so deeply in love with someone who just Isn't your soulmate. Something abt putting in the effort to build something where there wasn't necessarily meant to be anything, out of pure will and the determination to Love someone. Something abt the tragedy of that rare, beautiful construction then being ripped away by a universe that didn't think it fit within its own plans. Something abt their love being honest and real, and yet always being destined to lose.
