It’s representative of the shallowness of Victor’s affection for Henry. He’s obsessed with Head to a stomach-curling degree but also terrified of him, super possessive of Dick and constantly in a power struggle with him, and dismissive and borderline abusive towards Heart. So it’s hinting at the fact that he really only loved Henry in a shallow surface-level way, but was obsessive toward him like he was a possession, the way he treats Dick. Victor was also terrified of Henry (particularly of H discarding V) and the power he had over him, and was always grappling to be the one in control of their relationship, (even though it’s becoming clear that Henry obviously was and this power struggle was all in his head because Victor was a doormat). But at the end of the day, he never really cared about Henry’s true heart and what he wanted, just about the image of him he’d built in his head that Henry didn’t live up to. Henry was clearly a horrible person, but he was also financially reliant on Victor, so he might also have slept around to either (1) get Victor’s attention and evoke a more genuine emotional reaction or (2) destroy Victor’s image of him so he would finally let him go. The fact that the three entities have been brought back in such a way, especially Head, is like a grotesque physical manifestation of the real twisted “monstrosity” that were Henry, Victor and their toxic relationship. Heart being a big patchwork baby that’s unrecognizable to Victor could be an indication of how Henry kept his real heart hidden from Victor.
I just don't get how he's more attracted to Dick than Heart. This chapter wasn't even about Heart and they still found a way to slander him
