From Isaiah Joshua Chambers as Mystery Boy :
"It will be interesting to see if Fans can guess the relation between our two characters as the episodes go on... Cant wait for you to see my costume 👀"
@Mark A. Rivera , I know you are good for it ! ;)
Yeah my guess would be that he is Gaal and Raych’s son saved as a zygote during Episode 2. Not sure why that would be a mystery though. Are the foundationers not allowed to to know which children are there genetic offsprin? or will Raych never even make it to Terminus?
