The questions I have after my second listen (mostly Kalani related).
How does Kalani know that the red head was his Hannah?
Why does Kalani apologise for the tyre? Did he make it blow on purpose so that the wouldn't be able to take supplies back?
Is the second person that Scratch wants the rat? She would want the rat because she wasn't told about the helicopter and that changed everything.
Potentials for who it is Saul, Victor, Angel. Maybe as a LONG shot Kalani. On re-listen we don't actually know for sure Kalani died and he could be the messed up one they find at the end.
Very long shot I know!
