The dev team informed DMD fans before 0.18 dropped (May 3 before May 26) that some scenes had been omitted--reasons.
Lucas is a complete villian. Players thought Rachel was as well, but this is not true because she really does love D (in too cloying a manner, true). But, in 0.17 there appeared a new female villianess--Vicky. She is the female variant of Lucas.
Unfortunately, Vicky must have "not made the cut" in 0.18 because, although mentioned, she was never seen. I still eagerly await D exactly vengeance on that witch.
