Ren doesn't really speak so much when Nora isn't there. Not that Nora isn't at school it's just this year they're not in as many of the same classes, anymore. And so Ren doesn't talk as much, because it's harder, when Nora isn't there to act as a filter.
They still talk in class, sometimes, though usually they just take notes and doodle stick figures in the margins, staring intently at whoever the teacher is.
During the required study halls, they spend their time reading or doing homework, or doing reading homework, usually in corners or under a table in the computer lab on their laptop.
Blake is about as talkative. They're friends with Yang but the two of them don't speak as much as Yang talks to them and Blake fiddles with their phone.
It's a Friday when, seeking a place to hide from people in general, Ren finds Blake sitting on the windowsill of the back staircase, tapping away on a laptop, butterfly wing headphones an obvious fuck off. They're curled up in one part of the windowsill, leaving enough for another person, probably unintentionally.
Ren drops their backpack by on the floor next to the windowsill, and Blake looks up, and shrugs. They go back to whatever they're doing on the laptop, and Ren pulls out their book to start their reading.
This is nice.
