Why does Ana cry in the final scene?

She:
- is hurt by Robert’s cruelty to risk Daniel seeing the contents of the parcel?
- regrets not covering her traces (leaving the band at Robert’s house)?
- realises that she’s been exposed and will lose Daniel’s trust?
- regrets her reaction to Daniel neglecting her?
- is aware of the humiliation and pain Daniel must feel now?
- understands that her marriage is over (it wasn’t much to start with)?
