I think it's best to move on to the next scene now. They'll be in the Mysterious Beyond where those rocks are (like in LBT 4).
The question is what they'll be doing/talking about... We've discussed this a while ago (it's on page 7-8 I believe) and our results were:
- Redclaw encounter ---> how to get rid of him
- Talking about worries/Ali
- Earthshake & crossing a rift
So what do you think should be happening first? I'll just tell you what I have planned and then you might (dis)agree on it and you may add ideas

First one of them might pipe up with worries (eg. "Will we find any Night Flowers?") Then, all of a sudden, Redclaw finds them chasing them around for a while. Hiding behind a big boulder, they trick him discussing about how to get rid of him. Then they're talking about Ali for a while (they don't know she'll be there After a while, a sound sounds, Gang is wondering who uttered it --> earthshake --> tiny rift opens --> similar scene to LBT 2 if you know which one I mean.
At last, they arrive at the waterfall and the cave in the evening...
Oh, and we need to find people who will play Redclaw; Screech and Thus, and later on we need Loyfe's villains + Icky & Dil.
