i know this will probably lead to nothing and really more of spot the difference in these images (really nit-picky really), but it feels odd to say that this lu guang:
is the same lu guang as this one:
or let alone this one in one of the character profiles:
why do i think this? well, it has more with the nit-picking details i picked up from the clothing (the detail on the collar and pocket). for the very first two images of lu guang, he is depicted to having blue and black rectangle or stripe on his collar and one on his pocket, but on it's left side (although the watches are so switched too, so do with that information as you will).
not even cheng xiaoshi's outfit looks the same as it is not buttoned and has the pocket, but i guess it's a little change if you ask me. on the others, there is always a blue rectangle/stripe on the top part of the pocket, with some of the images missing the blue rectangle on the collar without the stripe or everything just missing (although it could just be to simplifying the outfit for animating it). however, for some reason, the vibes between these two lu guang are just not, the same? (if you catch my drift).
lu guang with the blue rectangles/stripes on both the collar and side of the pocket is always looking at the audience (which lu guang in most of these artwork does or looks away from the audience/us), with mostly similar vibes to lu guang in S1 and S2. yet, the lu guang with only the rectangle on his pocket is looking at cheng xiaoshi from below, with such a hopeful or innocent expression.
to me it looks a lot like wishful thinking, which he does a little (or most of the time) in the yingdu/bridon arc as he continues to keep cheng xiaoshi alive (at least). to me, it doesn't come off as the lu guang we've known (or at least developed into); more like his previous version of himself (who has made some mistakes in his own theories of perceiving time or to save cheng xioashi) as he's dived back in time a lot by now.
these little differences can be seen back to back (mostly in a second difference between each frame/scene):
although this could just be animation mistakes/errors in forgetting minor details, it's just so consistent in which details are missing or even the scenes it's missing from. perhaps at the end of this arc, lu guang thinks it was a mistake of bringing cheng xiaoshi to bridon this early instead of 2021 and tries to fix it in his later dives (S1 and S2), or perhaps is one of the dives he has abandoned.
