Holy crud, you're right! She has never been wrong (in any of her own books, at least).
[spoiler]4-She helped find Ax (vindicated!)
9-She nearly got stuck in morph to help skunks, but by the end of the books, all the Animorphs were helping her help those same skunks (vindicated!)
14-She doesn't really do anything here where she might be considered for vindication. But hey, if you count messing up military time as being wrong, she was wrong once in this book! But . . . no, that doesn't really count, does it?
19-She helped a Yeerk, who ended up turning into a good guy (vindicated!)
24-No big victories here
29-That Yeerk she helped in 19? Yeah, she helped save Ax's life (vindicated!)
34-Here, there were a lot of little things, like going against Aldrea's wishes when morphing away her wings when she was a falling from the sky as a humpback whale. But I'm pretty sure she ended up being right every time (vindicated!)
39-Cassie believes the Animorphs shouldn't kill the buffa-human. And what do you know, it ends up being helpful to their cause! (vindicated!)
44-Another one like 34, where she ended up being right several times in different ways (vindicated!)
50-Hands over the blue box, which makes a few Yeerks defect (vindicated, at least until Rachel gets killed by a freaking polar bear)[/spoiler]
