HISfirst name is up in the air, and surprisingly enough, so is his last name (ie. either solway or marcello). Both him and Vida were born in Montana and raised by both mothers (eventually moving to LA). While they were both born with Solway as their last name, Vida eventually had her last name legally changed to Marcello to match a specific mother out of the two (check Vida's app HERE for more info). The twins basically took care of each other while both parents were absent for a specific amount of time and after a while, Vida moved to Glenhaven to start her own life.
His personality, sexual orientation, place of residence, and occupation are pretty much whatever you'd like. I would just like it if the two still had something of a close connection and kept in contact. And while they would still care for one another, the sibling relationship between these two would be very blunt, not afraid to hold anything back, and they tend to switch back and forth on the "older sibling role".
His PB is also only suggested but if you can, try to keep him along the lines of dark hair and hazel, blue/green mixed eyes.
