Blood and Wine References (The Witcher 3: Wild Hunt)

In addition, a huge number of references and jokes. Share your observations. I have passed about half so far, but I have already noticed a couple of interesting details.
Firstly, the developers are clearly not indifferent to the "Game of Thrones". The final battle at the knightly tournament. The enemy clearly resembles Grigor Clegane, both in height and in name. In the city you can hear the phrase from the girl that her brother gave her a sword, which she named " Needle ".
In the quest with spoons, where you need to get the monster's saliva, you can read a letter that directly hints that the girl was bewitched by Gunther, and if we remove the curse and bring the old woman home, then when we talk to our house helper, the music from the first expansion will play conclusively proves that it was Gunther who put his filthy hands to this case.
