I think trying to stab Brandish in the back is not stupid at all. Sure we've seen people in Fairy Tail survive wounds that would kill a real-life Human, but even in FT they still suffered from such wounds to the point where their fighting abilities were reduced or they fell unconscious after the fighting was over. The most extreme such case is probably Jellal, who would most likely won against Natsu in the ToH arc, if not for the cut that Erza gave him.

Now stabbing with a broken key... that was indeed stupid, unless Lucy had some way to make it work regardless.

But what would you have her do anyway? Play along with Brandish's whims forver? At some point Lucy had to act and this was the best moment. Stabbing her, even if it's just with a broken key, still seems like the better choice than kicking, punching or trying to choke Brandish.

Summoning a Spirit or a Star Dress would likely have drawn Brandish's attention and it'd have been game-over for Lucy, even if Marvin wasn't blocking Lucy, but I think he was.

Now slowly getting the hand with the key next to one of Brandish's arteries and slashing it open like Derax-Pagani suggested would probably have been the smartest choice, but other than that or giving up, what other choice did Lucy really have in your opinion?
