Well. I'm not sure if this has been pointed out elsewhere, but anyway: In "Ab Aeterno", there's this short take of the Black Rock from over the jungle. Right in that moment you can see a black butterfly flying around. Then, the butterfly flies inside the ship and almost over Ricardo's head.
This may be absoultely pointless, but it's funny and intriguing. Is it just another insect, or something "darker"?
Any thoughts here, please?
