When she tried to attack Brandish Lucy had just learned that the only reason why Brandish kept Lucy around was due to trying to figure out why she seemed so familiar.

From that it's not much of a leap to assume that the moment she figures it out, she might very well get rid of Lucy. By then it would have been too late.

Little chance and stupid under normal circumstance or not, Lucy had to do something quickly or risk not ever getting another chance. And that Brandish remembered that very moment and turned on Lucy just goes to underline that reasoning. Lucy lost her one chance to act due to freezing up on Layla's metion, so ultimately it didn't make any difference either way, but at least she tried. Better to try and fail than to never try at all.

But there is one thing I don't understand in your reasoning Sane. What Laxus did in this week's episode was at least as stupid. He is barely holding onto life and yet he's rushing into a fight. A fight that literally the entire guild can fight in his stead, without him getting himself killed. Now THAT I call stupid.

Lucy on the other hand didn't have much of a choice here. Considering what Lucy knew of Alvarez she probably thought she was as good as dead either way, so better try to do something than just meekly submit to fate and let herself be killed once Brandish figured out where she knew her from.

As for the communicating with Warren: For what? As you said they knew her position already, so what good would that have done. Or for that matter what good would have literally ANYTHING else done?

As you say Brandish is feaking powerful so nothing else Lucy could have possibly done would have been of ANY benefit at all, no matter how long she played along. This was the best chance for Lucy to do something and as we now know the only chance and that alone more than justifies Lucy's choice of action in my eyes. And I came to these conclusions not out of banboying, but out of logical reasoning.
