Sylvia Sherwood/Relationships

Loid Forger
Loid Forger, as Twilight, is one of the intelligence agents under her command. She is extremely demanding of his spy abilities, frequently sending him on missions without rest due to the lack of manpower, but has been shown to worry for his well-being, since she uncharacteristically let him go on vacation since WISE was scolding her for overexploiting her agents, accepting that it was Loid's moment to rest from work (which surprises him because he expected her to refuse) and also allowed him a break after hearing how he collapsed in his home. Though their relationship is largely professional, the two appear to empathize with each other due to their shared experiences of the war.

When Twilight first joined Westalian Intelligence, Sylvia was his new commanding officer and was responsible for training him into a first-rate spy. Her extremely strict practices have resulted in Loid having a fear of her, to the point of having nightmares of her.

Fiona Frost
Fiona Frost, as Nighfall, is one of the intelligence agents under her command. Unlike with Twilight, Sylvia is not that demanding with Fiona, but she does send her frequently on missions, normally sending her to accompany Twilight and support him with Operation Strix. Though their relationship is largely professional, Sylvia seems to be very strict with her in some moments, as her true intentions of trying to remove Yor as the Forger's wife are somehow visible to her, so she constantly warns her to not plan anything reckless. However, as her subordinate, Sylvia cherishes Fiona and tells herself to not be so willing to get herself killed after the latter injures herself in her fight with Winston Wheeler. She is also aware of her feelings for Loid, which she finds adorable.

WISE Agent
Sylvia appears to have a good relationship with him, as she occasionally assigns him on missions with Twilight. Knowing that Twilight is her best-managed spy, she trusts the Agent to support him. Although their relationship is professional, they are shown to get along pretty well, as the Agent is not as frightened of her as her other subordinates, making casual conversation and jokes and chastising her for her slovenliness.

Yor Forger
These two share mutual respect for each other, although Yor has not directly met her as Sylvia since she frequently disguises to keep her real job as Loid's handler a secret. Still, Sylvia somehow feels fond to her as she knows Yor is helping the Forgers become closer, being the reason why Loid has become more open.

Anya Forger
According to Sylvia, she used to have a daughter of the same age as Anya; therefore, she is kind to her and proves to have a maternal side with her, allowing Anya to keep Bond as her pet and comforting her while promising to treat the bomb dogs well. When she saw Anya at the dog park during her briefing with Loid, Sylvia accepted the little girl's competition to see who has the best dog.
