SO I HAVE A THEORY
HI HOLY SHIT SO IK SO MANY PPL ARE THEORISING ABOUT SHIRO BEING A CLONE BUT HEAR ME THE FUCK OUT RIGHT NOW
“””REAL SHIRO””” IS THE CLONE AND THE SHIRO WE SEE IN S3 IS THE REAL ONE???? BC REMEMBER WHEN THEY WERE WITH ULAZ & SOMEONE SAID SOME SHIT ABOUT THAT THEY COULD’VE PLANTED FAKE MEMORIES IN SHIRO’S BRAIN ABOUT HIS ESCAPE & SHIT??? THAT WOULD TOTALLY EXPLAIN SHIROS AMNESIA & ALL THAT SHIT AND HIM BEING FAKE NEWS WOULD GIVE EM A GOOD EXCUSE TO PLANT THE MEMORIES AND PREVENT HIM FROM KNOWING HES A CLONE??
cos when long haired shiro is escaping he sees himself on an operating table (idk whether hes actaully witnessing this or having a flashback, its not totally clear bUT) - the galra refer to the procedure as “operation kuron” - “kuron” meaning “clone” in japanese. So the whole ‘shiro has a clone’ thing seems pretty viable.
so this scene is very much from shiro’s perspective when they put him in whatever liquid this shit is,, presumably to preserve him while they make however the fuck many clones of him.
say they decided to make multiple clones, they’d probs wanna keep him frozen in there with easy access to his dna for cloning and memory transplants & whatnot.
i reckon that if this is the case that the galra must’ve linked both their minds so that they have the same memories, and wouldve kept s3 shiro unconscious for a while, hence why he doesn’t know why he’s on a galra ship when he wakes up and explains why his hair is so gotdang long. It may also explain shiro’s persistent headaches when he returns,, this could be a side effect of having a chip in his brain or from having memories from his counterpart transferred to his (or maybe just a symptom of being sedated for so long).
it seems awfully convenient that s1-2 shiro had amnesia after escaping so would cover up any doubts about memories of being cloned/escaping etc.
so thats all for now and im sorry this theory probs has hella holes in it and im terrible at trying to intelligently communicate via words BUT AT LEAST ITS PRETTY DAMN CLEAR THAT WHETHER HES A CLONE OR THE OG - S3 SHIRO IS DIFFERENT ONE
