Falling on her back, she could feel the sudden adrenaline kicking in as she rolled.out of the way of a ice like mace that was about smash her and the armor if the young Stark hadnt rolled out of the way much sooner. quickly getting to her feet, she got into a kneeling position, charged her repulsors before firing the charging frost giant. Riza quickly got up after that to look and make sure she wasnt going to get jumped. But she did notice her father about to be jumped by two frost giants and charge her repulsors, firing at both of them, enough to make them stumble back and have time to run and help him. "Watch out dad!" She shouted, stopping.to charge her repulsors again for a bit longer fire, killing the two giants. She then tried to call Banner. Hoping the Other Guy could help turn the tables. 
Thinking upon what her father said, Riza wondered was North. Then it hit her. "Dad! Your Company! That must be their target!"
