After a second reading, I'm actually more annoyed with Leah.  Roxy asked her plainly what she wanted after admitting he might be reading her wrong.  Even if she doesn't completely know - since she tends to think more about what she can be doing for others - all she had to do was be as straightforward as she has been about everything else so far.  "I like you a lot.  You're the first person I've ever thought seriously about marrying even separate from the political need.  It makes me happy to see you smile.  Even if we don't get married now I would like to continue dating." Leah you've been doing so well up to now, including chasing him down at a party to tell him you like him, what held you back this time?
Also yes, please take your anger out on some horrible mustache-twirling villain that deserves it, so I can see the Power Couple destroy everything in their path.  :)
Thank you for spoiling us with the extra release Matcha!
