Rey explained everything to Esme, who listened in amazement.
He told her about how he had to mimic her—or rather, the style she adopted as Lux—though it wasn't very difficult to do since she didn't have much of a personality.
As a result, juggling two duplicates and their functions didn't prove to be too difficult. He was mostly focusing his sensory connection on Jet, while Lux was on autopilot.
Rey went on to tell her about the appearance of the Skeletal Dragon Lord, and how he was initially worried about its emergence.
Even after seeing its Status Window, he was still quite anxious since he wasn't at full strength, and he also wasn't the one in the fight.
"I also had a couple of clones still running around, so I wasn't at full strength."
That was why he left the first half to Adonis and his duplicate, since he wanted to observe the battle from the sidelines.
