If you own a "majority of the stock market papers" that IS owning the company. Each of those papers is a certificate of ownership of a portion of the company. When Walter says he was the "sole shareholder" that meant he is the only person who has those shares, i.e. the only person who owns the company. People are called the "owner" of a company when they own a much smaller percentage of the company than Walter has. I am fairly certain that Bill Gates owns less of Microsoft than Walter now does of Massive Dynamic.

What I wonder is what Nina did to piss off William Bell so much? The two portions of the will combine to say "Dear Nina, Thanks so much for running my company and making it into the powerful and successful corporation it is today. You now answer to a deranged lunatic kidnapper & child-experimenter whose primary agenda item is getting a cow to produce chocolate milk." I kind of hope she's been involved in massive embezzlement the whole time "Belly" was vacationing in zeppelin-land, because it would a. justify the royal screwing-over she has received, and b. it will give her something to live off of when Walter bankrupts the company with his magic beanstalk transactions.

It's not so much that she's evil, as operating in terra incognita. Just because he's deaf doesn't make him innocent - this is a criminal who broke into a house and is an accessory to the murder of the family that lived there, and stole something of national-security importance from his employers. He's a liability who could compromise a critical operation in enemy territory.

Indeed.
