Okay, so I have a weird nit to pick, from Episode 4. I doubt it needs spoiler tags, so I will leave them off. (a fair warning, that this is entirely an unnecessary nitpick over a prop...

lol!!)
For those that have seen that episode, they will recall the preparation and consuming of Absinthe. Absinthe is a favorite of mine, and its history is a tad exaggerated, and/or misunderstood. The "green" coloring, of the, shall we say, "the good stuff", is much more yellow/grassy in color. Generally derived from the botanicals used in the distilling process. The cheaper products, often got their "vivid" green from copper. Not a practice used today, of course. Those that are made nowadays, that have the venomous coloring, are just generally added dyes. The psychotropic effects that were sometimes described came from repeated drinking of a very high proof alcohol (which absinthe is), and the copper which can cause deterioration in the brain. Wormwood, which is one botanical used in absinthe, can have some rather nasty effects on people, but the amount used in making absinthe is so minute, it is doubtful to have ever had an effect (good, bad, otherwise)
The "looshing" that you see in that scene (the act of dripping water over either ice or sugar cube), causes the liquor to become milky. Absinthe is very similar in style to both Pernod (who was considered the original maker of Absinthe), and Ouzo. Both (along with absinthe) use anise as the main flavoring ingredient. All of them will turn somewhat milky when water is added. (as an aside; good absinthe is really quite smooth, and flavorful enough without the added sugar. When I loosh, I prefer ice instead. Goes really well with lamb dishes, and hard meats and cheeses. yum!)
So you can guess my nitpick here (and it really is irrelevant...LOL!) is that in the scene, the absinthe is vivid green (the cheap stuff), and it doesn't turn milky at all during the looshing process. I would have expected Dorian to spring for "the good stuff". LOL!
I think I may be bored right now.....sorry for the unnecessary essay.
