This scene interests me on a lot of levels. (The most superficial being that I love seeing men terrified and crawling on the ground, so, win there)
But this scene is funny to me because Newt does the classic thing that people (mostly women) do in horror movies, where they break a heel or fall over or something when running from a monster, and instead of getting back up and sprinting, they do this. I think it’s always a ridiculous trope, because survival instincts take over in a situation like this and really you’d get up and sprint. But what if there’s a reason for it here?
In the novelization, it’s explicit when Newt meets Otachi that he’s still ghost-drifting with her, still partially thinking with/for/like her. What if the same thing is going on here? What if the reason he doesn’t even appear to trip so much as throw himself down onto the ground and then crawl around like this is because that’s how Baby Otachi moves? You’ll notice in that first gif that Newt goes down at exactly the same time as Baby Otachi does, and then his crawling on all fours closely echoes what the kaiju is doing behind him.
When he turns over in the final gif, it’s like an assertion of some part of him through the foreign impulses in his brain—he may be down and crawling like the monster, but he’s at least going to look at it and see that it’s not him.
