After sectumsempra, they don't really interact much. Perhaps there's a moment in the library where Harry inadvertently sits down near her, looks up and sees her scars, and she, presuming he hates her, hastily gets up. She still holds him in her heart though. This kind of bond is not something that can be easily shaken, like in Malfoy manor where she doesn't give him away to the Death Eaters. But it's not until the fiendfyre scene in the room of requirement where the false reading from the sectumsempra scene becomes difficult for her to maintain. Harry specifically turns back into danger and grabs her, pulling her to safety. It would be the first moment after ss that the bond she had been carrying (making her fail at Crucio and later refuse to hand him over to the DE at the Manor) finally sees a reciprocity. xitter.cf/HalfTangible/status/21…
