I know Kase can't hear ^^ Arya doesn't really know though. She assumes Kase can still hear because she didn't really pay attention when with Rant and after Rant, she entered survival mode. She assumes again when acting like this and she doesn't really think too much into it. She may be a good strategist but when she's all pumped up like this, she doesn't think of small things like Kase's mic and radio not working. Sorry I didn't make that clear ^^'
Well after your post no one was posting so I broke the silence and yeah the two posts after you from me and DJae that's all that's happened out of your knowledge.
