In Game of Thrones s08e04 we see Varys and Tyrion having a conversation about who would be the best heir for the Iron Throne where Varys seems to try to conspire against Daenerys. Here are the last phrases of their dialogue: Varys: You know where my loyalty stands. You know I will never betray the realm. Tyrion: What is the realm? Vast continent home to millions of people most of whom don't care who sits on the Iron Throne. Varys: Millions of people. Many of them will die if the wrong person sits on that throne. We don't know their names but they are just as real as you and I. They deserve to live. They deserve food for their children. I will act in their interest no matter the personal cost. Tyrion: So what happens to her? Please ... don't ... Varys: I have spoken as honestly as I can. Each of us has a choice to make. I pray we choose wisely. What does Varys's last words exactly mean? What is he planning to do? Does he imply something specific?

How did another Engineer ship with a chest-burst Engineer and lots of facehugger eggs end up on LV-426 (Alien) when all Engineers are supposed to be dead before David created the first facehugger eggs himself? Wasn't the idea of Xenomorphs shown to exist before Alien: Covenant (2017) by the murals in the Ampule Room on the ship on LV 223 in Prometheus which might explain who piled up the bodies of Engineers on LV 223?

At the beginning of the famous Indian movie Jewel Thief (1967), Vinay (Dev Anand) is seen going to a jewelry shop and talking to the owner about employment. After being rejected, he steps out of the shop, and at the same time, the owner's daughter -- Anjali(Tanuja) -- is seen entering the shop. After this, there is a song sequence where Dev Anand encounters a group of girls (including Anjali) on a country side road. The song sequence suggests that Dev Anand was intentionally walking in front of the car to tease girls. After a little hustle, they are acquainted. Later, when Dev Anand is finally employed at the same jewelry shop, Tanuja pays a visit, and Dev Anand tries to sell necklaces to her. However, after a little playing she reveals that she is the owner's daughter, and Dev Anand shows as if he did not know this, and is completely surprised. Was the surprise true or false? Did he know her well and that is why he followed her after being rejected by his father? Was he looking for another way to get in, and then he tried to play it smart by pretending that he did not know who she really was? Or was it a mere coincidence that Dev Anand happened to be on the same road as Tanuja, and teasing some random girls soon after he was denied a job at her father's shop?
