Thanks to some sort of random alien nonsense encountered on some planet or other, Hux temporarily acquires mind reading powers.
Unfortunately for him, it's not like Kylo's force based 'stare intently at someone and dig around in their brain for information' sort of mind reading, this is "I can hear every thought that crosses the minds of everyone around me and it will not stop."
+ Kylo has no idea, what with it not being a force thing, he just knows Hux is in a worse mood than usual about something so he's not making any sort of effort to avoid thinking about stuff he doesn't want Hux hearing. ++ Hux has to give up public speaking for a while because large crowds are deafening. +++ The worst part is having to hear random crew members unfiltered and graphically explicit sexual fantasies, especially as he's apparently featured in some of them... ++++ Phasma is secretly mocking everyone. +++++ Mitaka's inner monologue is full of boundless rage.
