Our reading
An editorial interpretation.
Cordelia asserts that a feeling is mutual, then locates that agreement deep down. The wording expresses confidence in what another person feels without giving their reply. It presents reciprocity as something she knows, while the excerpt itself leaves that confidence unconfirmed.
