The Garrison knew all along that the crew on the Kerberos mission had been abducted by an alien ship. They covered it all up because they didn't want to cause a global panic. When Shiro managed to escape and return to Earth, they were going to cover that up too. I had to bust him out of quarantine.

Some kids from the Garrison happened to be there when I got him out. The next day, we found the Blue lion hidden on Earth and she immediately took all of us to planet Arus -- millions of light years away from home. That's how we all got involved in the war.

If Shiro could've told him, he would've. I know that.
