Tristan, paired with Libby Rhodes for the defense of the manor, initially underestimates her while privately admiring Nico de Varona's extraordinary range of physical magic. As armed intruders attack, Tristan discovers his own critical value: he can see through illusions that fool even Libby. When Libby fires at phantom targets and misses the real gunmen, Tristan realizes the room is flooded with illusory combatants and begins physically aiming Libby toward the actual threats. Together, they eliminate three gunmen and then track the illusionist medeian to the house's private chapel, where Tristan spots him working a laptop to hack security cameras while maintaining the cloaking enchantment. After a tense confrontation, Libby overpowers and kills the illusionist, though the effort nearly exhausts her.

Tristan and Libby regroup with Parisa and Callum on the stairwell. Callum reveals that he and Parisa dispatched the illusionist's partner, a hand-to-hand combat specialist, and that both medeians were operatives from a Beijing intelligence outfit. Parisa appears shaken, though she deflects questions about what happened with Callum. Nico and Reina arrive, and Atlas Blakely explains the full picture: the attackers included an MI6/CIA military task force (handled by Nico and Reina), the Beijing operatives (split between Tristan/Libby and Callum/Parisa), a Wessex Corp agent (dispatched by Reina), and two medeians from the Forum—a rival academic society—who failed to breach the library's defensive wards.

Atlas reveals that the Society deliberately leaks the arrival date of each new class of candidates as a longstanding tradition, using the resulting attacks to test the cohort's collaborative abilities and to evaluate how enemies have evolved. Dalton reinforces that the six were chosen as a team, not merely as individuals, and urges them to collaborate on future defenses. The candidates react with varying degrees of anger and acceptance.

Afterward, Tristan approaches Parisa privately. She rebuffs his implicit suggestion of spending another night together, warning him against attachment and revealing that something unsettling happened with Callum during the fight—though she refuses to elaborate. Tristan reflects on his pattern of being drawn to self-assured, emotionally unavailable women, and on his lifelong sense of uselessness instilled by his father Adrian Caine. He acknowledges that his ability to see through illusions made him indispensable to Libby, yet he still struggles with feelings of inadequacy.
