Parker's been having a blast (pun intended) ridding the world of exploding Bouncy Beverage. If this place provided amusements like this more often, she could survive well here. Explosions are fun.

When the door closes, Parker's ears do pick up a noise. Along with her reflexes, her hearing's excellent, otherwise she couldn't hear the clicks in the safes' locks. It's important for her profession, and if there's one thing Parker is, besides insane, it's a professional.

When Chucky does find her nest of explosives, there will be no one there. On the other hand, it will be so recently vacated, that the skin of an office chair upon which she was sitting, will still be warm.

She'll show up. Give her a few seconds.
