The girl is pregnant, this is true, and it is the brother who did it, there are two points to prove it: 1. From the perspective of the whole movie, the girl is very simple, but in the end, she said it with a gun and a serious expression, it should be true. 2. Earlier in the story, there was a picture of her brother sleeping and dreaming, in which his sister appeared three times, and once his sister was naked. It may have been at that time that the girl was fertilized and became pregnant.
Joe's JJ question, from the picture of her flirting with the girl, the girl moaned with an "oh", and it was said many times before that the girl was a virgin, which means that Joe didn't insert it, otherwise it must be a painful expression, and Moaning means that Joe just touched the sensitive part of the girl (below or breast, not in the picture) and failed to insert (normal people are like this, they will definitely enter), it seems that Joe's JJ really has a problem.
Finally, the film is educational in all respects.
