As one of the best Crows, Lucanis is used to making clever assumptions. It’s how he knows the team disturbingly well. Because of this, he knows people don’t trust him, shouldn’t trust him.

And to a certain extent, he would be right. Most people would be offended that he seems to flirt but keep turning away (see the almost-kiss scene).

But we all know Rook isn’t most people. Rook can be irrationally unhinged but Lucanis’s Rook can also see through and accept Lucanis’ need for space.

The whole first half of the “romance”, Lucanis tries to flirt while also second-guessing his actions and Rook’s reactions. He overanalyses and smacks his own head when he reviews his self-rejections and realises Rook IS responding positively.

And every time, he comes closer to believing Rook does reciprocate his flirting. It comes out in his expressions, it comes out in his speech.

Making Rook’s favourite dessert was the first time he genuinely tested his theory that maybe Rook does like him. But at the same time, he makes enough dessert for the whole team so if Rook does reject him, he can settle for having AT LEAST made something nice for the whole team.

When Rook spells out that they see Lucanis making their favourite dessert, Lucanis still tries to wave it off as they also made it for the team. But then Rook specifically mentions that obviously they know Lucanis would make enough for the team, but he made Rook’s favourite dessert.

Remember how he is still struggling to accept Spite himself? Rook and Emmrich are the few people who accept Spite as a part of Lucanis, that Spite exposes the rawest emotions of Lucanis. Although Emmrich does see Spite as its own being like Taash, Emmrich treats Spite like its own independent person.

Meanwhile, Taash treats Spite like a petulant child that needs taming, Harding and Neve are confusedly anxious, and Davrin is only half-joking about killing Lucanis if Spite takes over. (Expanding on the Neve-Lucanis romance later)

The coffee date where we “confirm” the romance? Rook sees Lucanis serving Spite his own cup and is pretty much like “yk what? hell yea”. Rook has always treated Spite as a part of Lucanis, and has partially made Lucanis Lucanis. I like to think the Lucanis who accepts Spite is the best one.

This is also what sets Rookanis separately from Neve/Lucanis. In the love scene, Spite brings out the wings. It’s a part of the love scene. Rook reassures Lucanis later that if Spite does come out when Lucanis is sleeping, Rook is more than comfortable entertaining/socialising with Spite.

In contrast, Lucanis sends Spite away if he and Neve spend spicy time together.

Yes, Rook sees Lucanis as a talented rich kid who deserves his Demon of Vyrantium reputation. But Lucanis’ Rook also sees him as the orphaned grandson of the most powerful Talon who feels like he had to perfectly embody the Dellamorte name at all times. Lucanis’ Rook has seen how Spite takes over, Spite’s powers especially nearly killing Illario, and still goes “that’s my man 🙂‍↕️”

One Emmrich-Lucanis banter moment has him confessing he has NO IDEA what Rook sees in him. Him - First Talon, Dellamorte’s favourite grandson, rich enough to have an in-house opera house, with all the charm and fitness of being the Demon of Vyrantium - confused that Rook allows him to feel like he is losing hours of his life because he wants to spend even more time with them? 😭
