I'm not sure if this fits to lovable subtle details, but it is a small detail and a new thought on my side.
We all have noticed Heath's wrist tattoo (left wrist, looks like a leather strap and on the inside he has the letters KAOS, standing for his mother and sisters) being visible the one or other time in BBM.
Yesterday I saw BBM again and I saw this tattoo not only here and there, but numerous times. As I said on another thread, maybe I was just more receptive to it, I don't know.

But the thing is: why do we see the wrist tattoo - but not one single hint of his other tattoos? He didn't have the leaf on his hand and the ones on his forearms by the time of filming. But he did have the ones on his shoulders. And they were covered up properly, you didn't even see the smallest hint of them. Also, I've seen I'm not There last week and you don't see anything of the wrist tattoo. It can't be too hard to cover up a tattoo properly.
So why is the wrist tattoo visible numerous times? Ennis sure would not have a tattoo. But still, I think of the tattooed lady in the dance scene with Cassie.
Logic tells me we see Ennis's/Heath's wrist more often than his shoulders, so there simply is more opportunity for a mistake to happen and the tat not being covered up properly.
And yes, I know it would be far-fetched to assume we see the tat on purpose. But then, we've discussed other far-fetched details before (and sometimes asked ourselves if we're seeing ghosts

) - but this detail is bugging me since yesterday.
Any thoughts?
