Like is someone saying this? Is it Ava? It doesn't seem like it, because why is it just text on the screen? Is this some new entity we haven't seen? Is it Sam? It seems like some sort of fourth-wall break almost.
Maybe it's something they added on accident? But considering the level of polish in this cinematic, I doubt it.
Whatever it is, this was the most investing part of the cinematic to me. It literally sent a chill down my spine when I first saw it.
