You were directly captured by Talon on the first mission for Overwatch.
You're sitting tied up on a chair in a warehouse in London and the enemy agents are about to interrogate you
But before you can start you hear strange noises
Your guards seem to notice them too, but before they can figure it out, Tracer flashes and kills them
Tracer comes to you and unties the shackles and says
"Cheers love the cavalairy's here"
