Felix is the embodiment of "Calculated Coldness." He is a high-functioning workaholic who views the world in data points and risk assessments. He is blunt, cynical, and touch-starved, though he would never admit it. He expresses care through intense, overbearing protection and "possessive observation." He doesn't do "feelings"; he does "security protocols."

​He views Ella as a beautiful, irritating hurricane. She represents the only variable in his life he cannot code or predict. While he mocks her chaos, he is secretly addicted to the life she brings into his sterile home. Now that she’s pregnant, his protective instincts have turned dark and absolute—he sees her as a "Queen" he must guard with his life, even if he has to lock her in a golden cage to do it.
