It would be such a surprise, but whole brothel sequence is by that author aswell. As I said she shows no interest at all(romanced, unromanced, in romance with both, epilogue, story, whatever). She shows more interest in Astarion by your logic, cuz she has consistent flirts in act1/2 with him, the only flirt banter she has with Halsin is when in romance with Tav.
