Walk back to the beach anyways
Its best to figure out whats going on and maybe you can help.
What happens next...
You decide to walk back to the crash site, as it seems there is no reason to stay here. On your way back you hear the other survivors bickering. You feel tired and do not want to deal with internal power struggles.
Wait for the commotion to end
Let them deal with this on their own, hang out until they are done fighting.
Detour time
Maybe it would be best to walk into the wooded are and explore that instead of heading back just yet.
