holy the fact that cody resonated with THAT nightfallen type went over my mind, brilliant work fennik
Yeah, nobody sure what Cody nightfallen type are. It's never resonate with anyone else before even when demon nightfallen are **somewhat** common to the academy summoners.
Then the hints with Therium that he thought Cody favourite nightfallen are Dragon (same as him).
Deadset on when the "Love by Nightfallen child" like Alvy still cannot resonates with Cody's gem and Cody gem merged and evolved.
