Alex couldn't be certain that Eternal Night would be useful in curing Alejandro's madness as he had no idea what had caused it in the first place.
However, with Eternal Night to calm the Rey's nerves, he proceeded to snap, utilizing Mindscape to reach into Alejandro's thoughts.
Within the mind, Alex was shocked at the level of damage that had occurred with Alejandro's metaphysical mind in literal shambles.
"What exactly happened to you?" Alex muttered softly as he pondered for a moment before instinctively gazing upwards.
Within seconds, it all began to make sense.
"You saw it." He intoned before looking back down at what remained of Alejandro's mind.
It was damaged but not impossible to fix and so, Alex, taking a deep breath, slowly healed the Rey, one step at a time.
Slow as it was, Alex saw progress and in that progress, he saw hope.
