This going to an actual lawsuit would be funny.
Now I'm no lawyer, and I'm not sure which juristiction this would even happen in, but Athy could easily get away with saying that multiple verbal contracts were broken and none of Jason's/The Company's ends of the deals were ever upheld, therefore she had no reason to believe that any contract or agreement between the two would be fulfilled.
Especially since Jason was nice enough to put it all in public writing.
