Re: Arranged royal marriage AU - I love the chow being incredibly loyal to Jyn. Imagine the entire household knowing that Cassian is a good man for the princess because the dog instantly likes him. Cassian doesn't have a clue that the dog is normally suspicious of everyone around Jyn and just thinks it's really friendly. Jyn pretends not to notice at first, because she's still not ready to accept she's married to the best and kindest man after her father.
The dog likes Cassian before Jyn does, actually, and she’s put off that the Chow–let’s call him Stormy–almost seems to favor Cassian over her as soon as they are married. Stormy sits in his lap, eats out of his hand, and growls at Kay, which Jyn would like to do herself but she can’t–she is the royal princess and there is still some protocol to which she adheres.
When Jyn and Cassian do finally come together, when they admit to one another that they have fallen in love, Stormy is a good little guard dog and stands at his master and mistress’s door and keeps away any staff that might interrupt the lovebirds from their precious private time together.
