In the present-day main story, MC's first encounter with Xavier occurs during an ambush at the Abandoned Research Base. She finds him apparently asleep — or resting — in the middle of active danger. When the situation escalates, the first Evol resonance between them occurs: her unstable 'Lost'-tier ability and his Light trigger an unexpected synchronisation. This is the inciting event of their present-day relationship, and the moment that begins MC's gradual process of piecing together who Xavier actually is.
