That single promise from Alex caused panic. All of the Kleinberg Industries's business partners backed out almost overnight. Logan himself started desperately selling everything he owned, clearly trying to scrape together cash and make a run for it.
Then, Logan disappeared. The Kleinberg Industries was suddenly adrift without a leader. That's when Sera swept in, bringing a team from Reid Industries with her.
They completely cleaned the house, firing a ton of the company's senior managers. Later digging showed that every single person fired was someone loyal to Logan or one of the other members.
Alex claimed he was just 'lending Sera a hand.' But look at the result: all those high-level positions left empty by the purge? Filled immediately by people from Reid Industries.
They called it 'temporary help,' naturally.
The official story was that once Sera hired suitable replacements, the Reid people would step back and return the jobs.
