Hey there! During a scene featuring the most famous stage of the xenomorph’s life cycle (I’m trying to keep this as spoiler-free as possible; if you are familiar with the Alien franchise, you know this particular event was going to happen), there appears to be an origami bird (or two?) on the dashboard in the bottom right corner near the windshield in the background.
It may have been there in earlier scenes, but I only noticed it then. It looked very simple; like a flapping bird or traditional swan. It was on screen for about half a second, so if anyone else has seen/is planning on seeing Alien: Romulus, take a look and let me know what you think it is! Have a great night! -sarah
