In this talk, I will explore the diagnostic power of X-ray reflection in unveiling the nature of super-Eddington accretion flows. In the first part, I present simulation results highlighting how reflection emission profiles are highly sensitive to wind kinematics and geometry. I show that incorporating multiple X-ray reflections within these winds can produce a distinctive double-peak line...
