Ithi'Ka's mouth works to form a warning, but training prevents her from doing so.  Instead, she springs into motion as she readies her bow-- there's no way to get off a shot in time, but her bow is in her hands by the time she reaches Kasumi.  Her slight form offers little assistance, but she tries to wrench at the grappling monk to move her from the line of fire, even if that means taking the crossbow bolt herself.<br/><br/>((Weapon wasn't ready, so... Preventing a sneak attack on Kasumi, and/or using Aid Another to +2 Kasumi's AC.))
