Natasha let the glass container that Alex was inside open up to release him...there were a few scientists that would clothe and escort him off the premises.  She didn't have the time right now to give him a full check over due to the crisis and so didn't know that he'd lost a portion of his memory during the containment period...a portion of his memory that had accidentally been stored in data form during the current crisis.  In the meantime, she noticed her broken gun and decided to work on a more individual design for it, wondering how it would work as a collar and wrist strap function...though it would be more expensive since they'd have to be mass produced.
