*OK, she probably doesn't know what's going on, just that "someone" is banging on her door...*
Doing his best to keep his voice calm (he twitches at the sound of the explosion), he calls up to her:
"OK, it's OK, baby. I'm gonna come up and get you and help you down. I know you can do it. You run that whole office; this is nothing. You can do anything!" (Charisma is 3, so that's one success)
Then he jumps for the fire escape. (Dexterity is 3, 4s cancel, so that's another one success. I lead a charmed life!)
