I'm talking about how all the big events happening in Nod Krai in the present is due to the fact that from the beginning, Columbina in the future had already traveled in the past, affecting our reality in the process before we even met her. I'm actually less impressed that the writers managed to pull this off without any confusion or plot holes and more that the story is actually filled with red herrings that want to trick you into believing all the interventions were caused by Nicole to distract you from the fact that it was always Columbina because back when Rerir awakened, we all knew Columbina was too weak to pull off a giant protective barrier so at the time we thought it was Nicole, and also we associated the yellow color with her powers.

Also btw, all of this means that the events of Act 8 were happening simultaneously with the events of previous acts all under our nose when we thought it was one continuous line of event, it was rather 2 line of events parallel to each other. I find this impressive too.
Okay, I need to talk about that *thing* in Act 8 to make sure I'm not thinking too highly of Mihoyo
