When the wolves knew that there are humans here that can be eaten, when the giant sloth found stomach full food over there, they have have come again and again to fetch more. The tribal should have come there to investigate and scavenge from the things that collapsed down the new sink hole.

Izzy seems to be a U-turn specialist. First she didn't want her dad, Gavin, to go down the sink hole, when Gavin wanted to go. Then she wanted Gavin to go down the sink hole, when Gavin didn't want to go. Then again, she didn't want Gavin, to go down the sink hole, when Gavin had been on the verge of going down. It is also surprising that Gavin listened to her each time and gave in to her current transient brainwaves. And later, when Gavin comes back to home after signing NDA, she asks her what about Mom and Josh. She could have thought about that even time earlier when she stopped Gavin from doing something to save Mom and Josh.
