I can’t find the original post, but someone said a while back that Rachel and Ax’s relationship is “you have to START the hard thing. You’ll have backup.” This has been living in my brain, and is now paying rent.
It is true at the end of #21. Ax gets Rachel. In #15, they go charging off to kill Visser One together. But in #19, he directs his anger at Aftran first, makes the first threat, and then steps aside for her. The relationship goes both ways, and here, it’s personal. Ax finds the outlet first, but he saw Rachel knock Marco down for speaking against Cassie when the last conversation she had with her was walking away in disgust.
This is Rachel’s fight, and she’ll have backup, but she has called for the first move, and Ax will let her be the one to make it. Both of them would hold if Jake shook off the shock and asked them to. In the end, they do. They are the most loyal and obedient soldiers of this little army - that’s why they would kill for Cassie even when she is beyond help. It’s why they choose not to kill for her.
Rachel holds the anger the longest. She has been cut the deepest by this book - she has been worrying for months about what it can mean for Cassie to not know what’s right. As much as she was hurt by Cassie suggesting she isn’t right, nothing could make her believe defending the people she loves is wrong. They have the power, she has to use it.
Ax doesn’t let his anger go and step away from Rachel because he wants this to end peacefully so much as to spite Aftran for calling him heartless. If Jake had made the call, he would have helped. Cassie demanded that Jake kill for her three books ago. His team wouldn’t have let him kill for Cassie now.
Marco is the only animorph who wouldn’t have killed out of anger in this book. He would have killed, and he wouldn’t have regretted it, because he couldn’t have solved things Cassie’s way. It was the only logical solution, and someone had to do it, and Cassie wouldn’t. But he also is working with the most information when they find a little girl crying over a caterpillar. He would have followed Jake’s orders if he had to. He would have killed Cassie , Aftran, and Karen alone if he had to. Instead, he stops the leopard, stays the execution, because he is the first to realise that CASSIE has done the hard thing this time. She has achieved the impossible in a way that no other battle in the war to date has, with spectacular self sacrifice that cannot allow him to view her as the selfish coward he wanted her to be in his resentment. They can’t be certain yet, but Marco chooses, before Jake, more actively than Jake, to let Cassie’s choice stand. She hit him below the belt, but she was right. Marco has to care about at least one Yeerk host. He cares about Tom too. And he will not let this little girl, Yeerk and all, die. Aftran and Karen are a threat to security, but life is hope, and he has been moved by Cassie enough to believe that someone who has been in her head would, however cruel they may be.
There is no question that Tobias would follow Cassie to peace. If Marco is the least idealistic because of his childhood, Tobias is the most idealistic in spite of his. Even more so than Cassie, because if Tobias can make the right choices and save the world in the face of the bitterness, he can matter. He knows this is the hard thing, and he certainly wants to stand by it.
They all finish the hard thing for Cassie in the end. If she will not be the one to do the hard thing, then Rachel will be the one to protect it. No animorph will start and finish a hard thing alone without first pushing the others away.
Even then, they will find each other and they will be there.
