Its not worth fixating on, since as already mentioned, they are basically just making observations that even though it’s obviously strange, it’s something he was born with. Just listen to the dialog between :25 and :36 and it says enough.yeah but, do THEY know of elder gods? Because it's presented to us, via Cole, as if supernatural stuff is not real. As he seems surprised by it. Eh, I dunno, I just, it feels like it stretches credibility given how precise the image is. A perfect circle, with a stylized dragon, just happens to be a birthmark on someone.
I mean I guess if they try and say "yeah but you have cats who have fur patterns of another cat on them" and other weird things that, similar to clouds, you can see an image in it. But, this is very much beyond that. It's not just "hey those shapes, when pointed out, DO look like a bunny rabbit, ON a bunny rabbit!"
It's a nitpick, I admit, I just, I feel like anyone skeptical would be like "yeah....ok so that feels like a brand to me kid, looks like one too. Too perfect, it's maintained that same shape as you got older and larger? Stretching out in perfect proportions ? Seems fishy to me. " But no, she's like "yeah, totally just random, normal human skin variations." *shrugs*
Again, it's not like I'm tossing a table and saying the movie sucks now, I just found that line a bit lame. Like they just couldn't come up with a good justification in the script, and just said "fuck it, birthmark"
Sonya: “He had the same markings as you Cole”
Clueless girl: “It’s a birthmark”
Jax: “Whadayou mean”
Clueless girl: “He was born with it”
Later...
Jax: “It’s not a birthmark Cole. It means you’ve been chosen.”
Now, if you’re mostly nitpicking the design choice to pass off such an unmistakable symbol as a mere “birthmark”, then I get that, but they’re being purposefully vague about the “mystery” surrounding it, so I’m willing to run with the choice to be a bit on the nose about its presentation for reasons. And again, this is a series with stuff like a 500 year old, four-armed monstrosity that speaks English and lives on an ancient Chinese island.
