In general it can be very difficult to identify which characters are used in promos as they can be both morphed and have a texture from another character applied. Some vendors have their own unique character

In this case I actually think there are two different characters, or at least two different textures (look at the eyebrow shapes/colors).

As for Thorne one of them might be or be based on Scotlyn (DAZ).
