Rook’s ability to fulfill his duties as vice-housewarden may be questionable: When Vil describes Jade as “a gifted secretary who fulfills Azul’s every wish” Rook says he is becoming jealous, to which Vil responds, “You’ve never once taken on the role of secretary, so the comparison is moot.”
When Vil assures Jade that the rumors about his capabilities were true, he also adds that “Rook could stand to learn a thing or two.”
Vil is suspicious of how Epel will conduct himself in Fleur City, and when Rook assures him that Epel will have his full support Vi responds, “You don’t exactly inspire confidence.”
Rook says, “I implore you to forgive me for leaving you alone in such a way. I leave you this flower ere my departure. I shall return by the time this bud blooms. Please, keep it and do not forget me…” (Vil: “You do realize you’ll be gone 72 hours, not 72 weeks, right?”)
After the drama of Glorious Masquerade Rook is moved to tears, telling Epel that he will regale Vil with tales of Epel’s exploits.
Vil describes Rook as “quirky at times” but says the he turns a blind eye to it, “For now”.
Vil threatens to remove Rook from his role in a bid to keep Rook from bothering Leona, and Rook assures him, “I’ll tread carefully to avoid getting sacked. I happen to quite like my position, you see.”
When Vil and the rest of the overblotters are kidnapped by STYX Rook pursues them on the excuse of needing to provide Vil with skincare products to ensure he is ready for an upcoming photoshoot, but he later admits that he hadn’t been able to stand by while Vil came to harm.
Rook successfully reaches STYX and delivers Vil’s skincare products and Vil observes, “I thought I was used to Rook’s antics, but this truly takes the cake…Rook can certainly be eccentric, but once you get used to it, you see he’s quite affable and honest. Honest to fault sometimes, and utterly devoid of tact…”
Vil notes a “special serum” amongst the products that Rook has managed to provide him, taking it with him after escaping from his cell at STYX, and the serum is revealed to have been under Rook’s unique magic and acting as a homing beacon for him to locate Vil.
