Kasumi forms a crude mental shield as she was trained, and the energy leaves her reeling, but mostly intact. ((Will save 15, 8 damage)). Seeing Ithi'ka, she nods, says rapidly, "Pardon me please!" and grabs the dark elf's hand.  Pulling the much smaller woman over onto her back, she begins running at top speed down the stairs and out of the building, diving down the last feet from the window, she rolls with the impact, shielding the drow with her own body.  She then takes off running again towards the fence with barely a pause, lifting Ithi'ka to her shoulders as they reach the wall, then going her a strong push to reach the wall's lip.  Even as she does so, she summons wings on her back, and looks back to see if Garrett has followed.  ((Kasumi has the run feat and 35 base movement, and so is probably ahead enough to toss Ithi'ka up to the top of the wall, and still get under the window in time to catch Garrett.))
