You watched Red Son from a distance as he struggles to keep the Skeleton Key away from Mei and MK. Frantically using anything in bud arsenal to get away.

You were hired by Red Son’s parents to watch over him and to see if he got his job done. However, you also couldn’t let your presence known by MK and Mei so they couldn’t defeat you either, unless Red Son is in some dire need of saving.

This became an issue when Red Son was on the ground, looking at MK with an angered look. MK had taken the key from him, and was probably gonna return back with it. You had to do something, even though MK and Mei were there.
