Given scene/plot descriptions from movies or TV shows, and given a specific question about the scene, summarize the question into a title

In the trailer (NSFW) for Season 2 of Skam, Noora is shown waking up naked in some strange apartment after what seems to have been quite a crazy party.  In the actual season, however, I don't recall that scene ever taking place. Moreover, I don't see any place in the chronology where that would really fit into the story either. It resembles episode 9 a little bit, where Noora wakes up at Niko's place. However, in that episode, William wasn't there, yet William shows up in the trailer.  So, I'm not sure if the trailer fits into the chronology at all. So, what is the deal with the trailer? I remember reading about the creator of the series saying that she used to change the story as she went. Maybe the event from the trailer was originally intended to be a part of the story, but then it was changed?
Does the morning after scene from the trailer of season 2 of Skam fit into the actual story of the season?

General spoiler alert so I don't have to hide the whole question...  Towards the end of Avengers: Infinity War, Thanos uses the time stone to rewind time and reassemble the shattered mind stone.  We know that Thanos only retrieved the time stone moments ago on Titan.  We also know that using the time stone is not easy, and requires significant training and ancient knowledge, as noted in this Doctor Strange scene:    Mordo (referring to the time stone):      How did you learn to do that? Where did you learn the litany of spells required to even understand it?      Dr. Strange:      I've got a photographic memory. It's how I got my M.D. and Ph.D. at the same time.      Mordo:      What you just did takes more than a good memory.  You were born for the mystic arts.     Given the above, how does Thanos know how to use the time stone?
How did Thanos know how to use this item?

In The Fellowship of the Rings Galadriel gives each member of the fellowship a gift, many of these turn out to be critically useful in their quest:   Frodo's light saves their life in Shelob's lair Sam's rope is used in emyn muil The broaches lead Aragorn to the Hobbits The cloaks hide them more than once   There are two instances of foresight in the films, the first is Elrond who can see Arwen's future (and indeed Arwen herself). The other is Galadriel's mirror.  Are these random gifts which may come in useful or are they specifically given for challenges she knows they will face?

Can Galadriel see the future?
