Course, we are in a free world and we are all special snowflakes... I forget that from time to time. So, here's my idea : Derek is actually a psycho, because his sister were bullied for her gay drama. Also, his beloved sister and his father's relationship were really bad, this gave Derek a trauma. Proof? His lack of decency and the habit of not wearing a shirt. These are all evidence for him being a psycho. He also gave it away with him talking serious about MC about Maya. Find this idea dumb? Too bad, I can think what I want, you can disagree with me but you can't argue with me about it. It's a free world, can think what I want, lol.
