S1 E12 : Imma's burial plot hole X3

I liked season1 as a whole but there was three plot holes right at Lady Imma's burial:

1. The old clan should have noticed just like Ciro that the Young clan was not present at the burial;
2. The old clan should at least have noticed Ciro running away from the burial;
3. If the Young clan was not present at the burial they should have already been at Ciro's place.
