uhm, two quick questions one because I could need it and one because I can't remember :/

1) Has Kate ever had a gun to someone's face/shot said someone? I know that she always handles guns but right now I'm failing to remember one time in which she was face to face with someone pointing a gun at him/her. Maybe in that episode where she robbed the bank, but I can't really remember how that turned out.

2) Does/Would Locke have a constant? I don't know if Helen could be made of 100% constant material.

I could use 1 while 2 is something I could also ditch if I don't find a satisfying way to do it.
