¿Que hiciste? Lo que tu no....
Seems like it says "What have you done?" (what did you do) "What you wouldn't". and like it Spanish they might not say wouldn't like we would, or at least we wouldn't say no or not like this. It's interesting.

what have you done!
Like in Tommy boy when David Spade's character opens his door at the gas station and Tommy Boy says, "what'd you do?" Good point jeezzle!! 
Well I think they both work for either Jason. Context.. he shot the guy that was dying, the guy runs in and yells out "¿Qué hiciste!!! what did you do = what have you done! Guy says "Lo que tu no........." what you wouldn't do. (kill the guy and put him out of his miserable existence).
I'm thinking that usually the question is referring to the day so, "¿Qué hiciste hoy?" would be "What did you do today?" "What have you done?" is more like "¿Qué has hecho?" Interesting thought.
