A nice detail about the game is after you visit the Scriptorium and get Salazar Slytherin’s book, you’ll notice the once blank chalkboards slowly fill up with Sebastian’s research in the Undercroft.
You can see him desperately looking for a cure and angrily drawing X’s, scribbling everything he can and erasing some parts. You can even see the symbol of Ancient Magic.
He writes in Ancient Greek, Phoenician, Aramaic (an older sister language of Hebrew aka the language Jesus spoke), Cyrillic and other languages I can’t make out. As well as Alchemy symbols (a “secret” subject reserved for older students at Hogwarts.) You can tell both of his parents were professors who passed down their love of learning to him.
He also seems to have an interest in Astronomy (this could be where Sebastian and Amit being friends comes in handy), as well as Geometry and other esoteric things. You’d think he was a Ravenclaw looking at it.
Interestingly, Sebastian’s name is also Ancient Greek in origin. (Sebastian comes from the Greek name Σεβαστιανός / Sebastianos.) His uncle Solomon’s name is Aramaic and Ancient Greek in origin as well. (Solomon’s name stands for “Peace” = shalom, which could probably be ironic in this case. But it could also stand for Sebastian literally destroying the peace between himself and Anne after he kills his uncle.)
In fact, the spell “avada kedavra” is a different spelling of the Aramaic phrase “avra kehdabra” = “I will create as I speak” or “perish as I speak.” (This is where the magic term ‘abracadabra’ comes from.) It’s fitting that Sebastian was the one to cast it, considering he’s fluent and it could possibly tie into his family’s background.
The way he looks at us like you CANNOT tell me a romance option wasn’t in program. Also one of the developers a month ago, when asked via text if Sebastian has a crush on MC, answered only with this “👀” emoji.
