Kamina hadn't even really bothered with his phone until being stuck in that box. Even then, a lot of it just doesn't register. Yoko or Leeron would be great with the thing, but he's not exactly the reading type. Honestly, if he hadn't accidentally discovered the text-to-speech button on his phone, most of what was going on would've gone right over his head both literally and figuratively.

"That box wasn't big enough for two days of air," he says like someone who would know. "So I guess Fear did something to keep it coming. It'd make sense for that asshole. Everyone says he's just trying to scare us, not actually murder us." He's picked up on a bit, from listening in and talking to people. But just because whoever's buried here isn't likely to straight-up die doesn't mean he's going to leave them there, so Kamina plants the shovel and starts digging.
