It seems kind of likely doesnt it? And Claire mentioning that Moon senses it even stronger could be because of the pairing (3 and 4), Claire's strange powers have to come from somewhere i guess and the Sicae-MC could be her pairing and got the serum injected too?Dev Claire said to jess that I always felt connection with mc (kai) is that mean she also part of number series?
if yes then what's her number
Were Number 1 or 2 mentioned/shown in Moon's flashback? Maybe they got a first and more experimental version of the serum injected and thats why they are kinda fucked up and seem to have some kind of connection too?
