Me not wanting Seb to leave is just because Seb leaving won’t erase him. Seb will always exist, it’s just a matter of where; with Robron or away with Rebecca. If he’s Robert’s son then he’ll always be Robert’s son, regardless of where he is or if he’s on the show or not, Robert will always have a son. The thought of him just being some distant thing, like how Archie is to Jai or how Kyle was to Cain for years, I just hate the thought of it. Robert having a child he never sees and is rarely or never mentioned, and if Robron went on to have kids there would always be the fact that Robert already has a kid out there hanging over them. Getting rid of Seb out of the show/Robron’s lives won’t actually get rid of his existence. I’d rather he exist in Robron’s lives as their son than exist as a far away thought, only to inevitably return to cause drama. If Robert has a son I want him to be a child Robron raise together and work through together, making Seb something that brings them together, rather than treating Seb as the perpetual obstacle the show sends away to erase the consequence of a storyline they want to wrap up.
