Merci Brokeplex!
It could be as you say, in your post.
I tend now to think that Lureen had to hide Jack from the criminals that she had seen who wanted her husband's death !!
That would change the ball game, would it not ? In that line of thought as an issue and considering the ashes, Lureen also needs to protect the ashes, if Jack is dead; she has to do so also from criminals, but will not from Ennis but just for now, she does likely temporarily !
Au revoir,
hugs!
