Tyson has a plethora of phrases to fall back on to make it easier for him to communicate, but he also has an endless well of quotes and poems that he can draw from if need be.
Many of those quotes were drilled into Tyson at a young age, and he certainly doesn’t believe in letting skills go to waste. Tyson and Jethro would be sent to bed without dinner if they couldn’t correctly recite the phrases randomly slipped into their lessons by their tutors.
His taste in poetry comes from a much younger Tyson. Where most of Tyson’s other media tastes are generally happy, to drown out the bad, his taste in poetry is much more bitter. Those tend to be easier to express. A mask made from his younger self.
