Not really Furious's style to abandon the fight, even to get to the hostages. He's like a dog with bone when it comes to a challenge. The character is supposed to be intelligent yet hot headed, his arrogance and youthfulness blinding him to the bigger picture. In all honesty I shouldn't have had him notice the hostages as he would be too determined to beat Chrome now to even remember about them, or notice the rest of the team closing in on the bus. 

I'll change the post, but have him continue attacking Chrome when he should be charging the bus.
