Javi and Molly found a strange device with foreign markings on it. Whenever they aligned the markings, the person holding it (Molly) exited the gravitation pull of the strange forest and began to fly. This is important because not only are they in a strange place, but that same place also has mind blowing items on it.
Whilst Molly was in the air, a small pack of birds who they had never seen before started approaching Molly while making a loud screeching noise. This is important because it shows that this forest has other species of animals living in it than Earth.
The birds violently surrounded Molly and began to peck and claw at her clothes and face. This shows that not only are there new species in this forest, but hostile ones too.
