[Padme and Han Solo (Rebel, YT-1300)]

If Han Solo rolls two focus results, does Padme stop him from rerolling all of his dice, or can he still reroll all but one of the focus results?

[Vader Crew and Nash Windrider]

Darth Vader as crew allows you to choose a ship at range 0-2 at the start of the Engagement phase, and have them either remove a green token or suffer a damage. Nash Windrider says during the engagement phase, after a friendly ship at range 0-3 is destroyed, he may spend a charge and have that ship engage if it has not engaged during the phase already. Since both happen in the Engagement Phase, can you use Vader to destroy a friendly ship and then have Nash allow it to engage immediately? If so, when does the destroyed ship shoot relative to other initiative 6 or initiative 7 ships?
