I haven't managed to find the maid brunette at all, not even in extra. Unlocked everything else too. Anyone had better luck?
Also, I want to make sure I got the ending right. Ex-ill got rid of the scientists and stuff, both doctors got their revenge... but then it turned out Ex-ill wasn't 100% perfected like they though and her metabolism went berserk, creating more and more clones. After a bunch of tries (time skip), both doctors are forced to give up on Ex-ill and kill her before it goes completely out of hand. Was that right?
