Mafia 106. Cradle of Dragons

Fagus changes himself into Pet. This is prohibited by the rules, and the action does not take effect.

Result: Fagus fails. Am I right? (yes, I should ask again)

only the first action in order is changed. The same applies to stalking and checking the type of ND.

When doubling, the player has two actions, which may well have the same order. How do we select the first one?
By the way, there is also a question here: does doubling an ND necessarily mean the same ND on different targets, or can two different actions be applied?
