Ahhhhhh! Jaime looks like a monkey! He's no have wayland why the guck would try cast him!?!?!? Ahh his forehead is to big!!!!! Ahhh he looks like a monkey....not watching the movie. I rather stick to my imagination! Fuck Jaime and fuck this stupid movie. Ahhhhhh!
I think he should have his British accent, I know in real life as a kid Jace probably would have lost it, but it would show that unlike Izzy and Alec, he didn't grow up with them at the institute. Plus it will really emphasise his little doubts about actually being a Lightwood.
