Rasputin thanks you for retrieving the files and apologizes for not disclosing their existence earlier.
"To do so required a level of trust I have not held for a considerable time," he explains.
He goes on to liken you to his Seraphs, special Human agents he entrusted with advanced armor and weaponry. Though he admits to making many mistakes in the past, he considers you proof that trusting humanity was not one of them.
Rasputin vows that no matter what the future brings, you and he will face it together.
