"Left cross. This sucks.”
This is where I come to the conclusion that Cass’ abilities to read people hasn’t completely disappeared but is instead just buried underneath her new interpretation of the world around her. At split second intervals, she is reading everything Shiva is doing while most people in the restaurant haven’t yet noticed that something has gone array.
The difference is, she has to first think of the words for what is happening rather than just intuitively placing things into motion in her mind. It’s slowing her down. It’s like when someone speaks another language you’ve studied before but are not yet fluent in. There is that hesitant moment where your brain must first process it as something it understands on a base level (like English or whatever your native language is) first before it can react to it.
And even then, some things are difficult to translate. My grandmother has been in America for over 60 years, and her instinct is to use German for math still.
That was the actual barrier when Cassandra still used body language as her base language set. She had to first translate everything into body language and most abstract things, such as articles and speech patterns, did not translate so she could not understand them.
Currently she is experiencing an inversion of that problem.
