Bashir said in DS9: “In Purgatory’s Shadow” that the Breen didn’t have blood, but considering they never took off their suits, how did he know that? And if they don’t have blood, how does circulation work?
There are animals that don’t have circulatory systems, but they’re usually of a very simple order like sponges, nematodes and flatworms for example.
So either the “fact” that the Breen have no blood is misinformation, or they have something else that substitutes for blood.
Some invertebrates have circulatory systems which carry hemolymph, a fluid made most of water and contains various substances like carbohydrates, lipids, amino acids, etc. It’s not blood, but it still serves a circulatory function.
Well, the Genesis Planet did do something similar in ST III (keeping it vague for spoilers), but that one had a body to work with.
As for 06107.2, it could be a birthday (June 10, 1972), but the only reference I could find to that was the birthday of a background actor on ENT named Bobby Pappas.
It’s definitely not coincidental, considering that “The Inner Light” is one of the most famous episodes of the series. It’s a pun, a play on words in relation to the TNG episode title. It doesn’t have to have a thematic connection for it to be a title.
