I think going by Act 3's true ending I do think Hornet loves Ghost at this point. If you read Lost Lace's Bestiary Hornet notes she Doesn't want more children to be lost to the void. Even then I think the act of Ghost saving Hornet would inspire feelings of affection for him.

Ghost definitely cares for Hornet considering Act 3s true ending.
