Did Judy die?
This might be thinking too much about it, but at the end when Alan and Sarah are trapped in the floor, a plant rips through the floorboards and shoots Judy in the throat with some sort of colourful spine.
Afterwards we see Judy straight-up collapse. After that scene, you never see her again. When I was younger and watched this movie, I truly believed she'd died from the poison. We learn earlier that those plants are highly dangerous, and Alan warns them all to avoid them. Then when Judy gets hit, she collapses. She talks to Peter briefly, but again, after that we never see her again.
Did anyone else feel the same way? Even watching it today, that seems to me what they were implying by not showing her or Peter again, that she'd actually been killed by the plant.
