Probably can discern it's aim just fine, yeah.I mean... it shifts it's weight. It has it's arm cocked back. Does she have any idea where it's going to try to hit? At all? Face. Chest. Stomach..... anything?
Depends what subtle cues would need to precede such a movement. Given that it's probably going to shift from move to move rather than carrying them out entirely separately, it's going to be preparing to do whatever comes next as it does the first thing.If he decides to stop his punch mid throw would she be able to tell before hand? Or would she be forced to wait until after the fist stops?
