Emmerdale - Current Episode Discussion - III

[Son of Cain]

Don't know why the police are surprised that Emma did not leave a suicide note, after all she was running about like a demented banshee before the doing it, so was unlikely to be carrying paper and pen with her. She did leave a note in the church with the baby, but the police do not know about this, and it seems to have disappeared.
When she ran away from the barn fire she was not carrying her bag, so how did she hire a car, did she keep her credit a card and driving licence in her pocket. How could Ross find the bag near the viaduct, unless she went home to collect it when she left the baby in the church. Unless I missed something none of this makes sense.
