Whilst Brit and Mallick both got their arms sawn in half, they didn't completely lose them. Plus, Mallick seemed a lot meeker in this film after his ordeal, (quitting drugs probably helped too) while Simone was more than happy to voice her opinion since she only became more bitter after hers. But, Brit would definitely have her arm in a large cast just like Mallick. I might be mistaken about this, but I think I read somewhere that she's doing well and managed to find a good, honest job.
