When you first encounter Amygdala, I feel like the room was empty, then you try the gate and then she snatches you up and you get the intro, but in
this video you can clearly see her above the door on the way in. I feel like there's no way at all I would have missed this on the way in, she's not exactly inconspicuous. But at the same time, the person in that video doesn't do anything different and still tries the gate, gets snatched just like I did.
So what gives, and did I miss out on something by not being able to see her on the way in?
