Yeah, I ship it, them arguing with each other was peak

Same, they're just incredible together. Natori and Lapis tend to act meek, hide things. On the other hand, Diana and Alexandra are blunt, in different ways, and seeing them clash with each other ? I'm in love. Not just Alexandra either - Diana shines more brightly exactly in this kinda of dynamic, when she's calling things out as she sees them. And that reaches Alexandra, to have someone, for once, talk to her straight !
Besides, those two hooking up could have marvelous implications for the story, building up the "Diana got closer to the noble faction than in the original story" that was already in motion, while tying her to someone who doesn't give me chills like Rubeus does. Especially if the two of them end up supporting Lapis together, as noble and commoner. That could be fantastic.
