So I’m watching the very first ep again and realize that when Shiro crash-lands and gets taken in by the hazmat crew he’s wearing what we learn later is his gladiator/prisoner getup:
but immediately following the rescue and subsequent getaway (during which he is out cold and still obviously in the same clothes) we see him the next morning,
clearly wearing his own clothes.
But where did they come from??
The other three paladins-to-be left the garrison with just the clothes on their backs (and lbr Shiro’s height and shoulder-to-waist ratio means he’s not going to fit into anything of theirs anyway), and there’s absolutely no way he’d fit into anything of Keith’s either for the same reasons.
That outfit is also not generic officers’ or instructors clothing from the garrison either, because I’m like 95% sure we see examples of both earlier in the ep:
Which leaves only one obvious explanation:
Keith has some of Shiro’s clothing.
