Schlock, which part of "under cover" don't you understand?
You're supposed to be a circus performer, sneaking up on an old adversary and scaring an autograph out of him is not part of the cover story.
He remembers you as a mercenary, and people might remember him saying that. Word might still get out. Our cover might already be blown!

Priceless. And I think he may have peed himself just a little.
