: Struggles with an erratic, involuntary transformation. His shadow begins to reflect a monstrous, Alpha-like silhouette (reminiscent of Peter Hale), signaling his internal loss of control.
: Experiences severe night terrors and sleep paralysis. His primary symptom is an inability to distinguish between dreams and reality, manifested through "word blindness"—the literal inability to read or process written language.
