I think there should be a scene in twp where Emma, Kit, and Ash all stand in a room together and cause Julian, Ty, and Dru to simultaneously come to the horrifying realisation that they all have the same type (blonde. Jace Herondale adjacent.)
julian: i've spent years protecting my siblings, but now they're growing up and i trust them to make good decisions 😌
ty: *starts dating the thief and con artist wanted by all of faerieland who broke his heart after helping him perform illegal necromancy*
julian: .... hmm
dru: *starts dating sebastian morgenstern's son who was raised by jace herondale's evil clone and has magic land-destroying powers, the ability to compel emotions, and a shady moral compass*
I feel like there's so much plot potential for Ty as a Centurion. Since both he and Kit will be 18 at the start of TWP there's a good chance he will already be a Centurion. The Centurions are shown to be around Emma and Julian's age (17 as of LoS) when they appear in Lord of Shadows.
So, what if Ty has just become a Centurion when TLKOF starts? This would give him unlimited access to the Spiral Labyrinth's libraries and the Silent Brother's archives. This is added with the already extensive research he's done while at the Scholomance and the things he's invented. With Kit's powers and connections to Faerie would make them some of the most powerful Shadowhunters ever written. Not to mention that Ty also has connections to Faerie through Mark, Kieran, and Cristina.
However, as a Centurion Ty will have to report directly to the Scholomance and The Council with vows that require him to tell the Clave the truth. He's also forbidden from sharing any of the information that he learns at the Scholomance. This could complicate Kit and Ty's mission and could make for an interesting point of tension in the plot. I know that the Clave is different now with Alec at the helm but he still won't just allow things to slide. Necromancy is a huge deal, evidenced by how Magnus reacted to Ty doing it. There's also the fact that Diego Rosales, one of the most famous Centurions of all time, will be the Inquisitor during TWP. I don't know if this will help or harm Ty but I imagine it will affect his situation if were to ever have to face the Clave (which I'm very sure he will at some point in the series).
Since TWP will involve the greatest threat that Shadowhunters have ever faced it will take the greatest heroes of the entire chronicles to defeat it. I really think this could end up being the TWP gang and their collective powers. I didn't even mention the powers that Ash has and all that Dru will have to offer to the series. Neither did I delve into the powers that Kit has or even touch all of Ty's strengths. I feel like TWP as a whole will be the most epic series yet and I'm so ready for it!
Don’t y’all ever forget that The Wicked Powers is a ya fantasy saga about fighting demons and princes of hell and NOT a romance comedy drama about a sassy blonde guy, his foster family, his soulmate, his soulmate’s emo sister, and the ghost they raised?
i want ty’s pov so bad like i want to know what was going in his head; when he put a knife to the throat of the kid in the basement, when he slept in front of the door of the same kid at the institute, like we know he kinda wanted someone to solve mysteries or whatever (like kit said, you want a watson for your holmes?) but he had livvy for that right? it’s said that he and livvy were so closed off together that they didn’t even include dru (but than that might’ve been some siblings thing because sometimes yeah at that age you kinda are annoyed by siblings in general lol) but yeah i want to know what was it about kit that just made ty drawn to him from the start
