Q: Why wasnt Agent J still injured? Towards the end of the third installment of Men in Black:

 Agent J rushes the older Boris the Animal, getting his several times with his spike weapon. They both fall a great distance, Agent J activates his time machine, and then he reverts back to just a few seconds before attacking Boris (and miraculously healed). 

Why wouldnt Agent J still be injured from his encounter with Boris the Animal?

A: After having read multiple interviews with the Director and Producer (such as this, this, this, this and this) claiming that their inspiration for the time travel sequences was Back to the Future the only conclusion I can draw is that the ending was just a straight ass-pull, one assumes as a result of the persistent script problems that plagued the film and the writers inability to come up with a workable ending for the film.

*Theres absolutely no indication that the time jumper has the
ability to send a person back along their own timeline.

*Theres absolutely no indication that the body of someone travelling along their own timeline would de-age

*Theres no indication why someone whose body has de-aged would remember the events that immediately preceded the time jump 

*Theres no indication why this effect only works on J and not Boris

*Theres no indication how J was able to work out this amazing new
feature despite having only had a few seconds training on how to use the device.


In the words of Barry Sonnenfeld

We knew starting the movie that we didn’t have a finished second or
  third act. Was it responsible? The answer is, if this movie does as
  well as I think it will, it was genius. If it’s a total failure, then
  it was a really stupid idea.”





A: This is not something canon-supported, of course, but it can just be possible that the time-travel device functions differently depending on some factors we dont know about. Maybe it returned Jay back to the physical state he was in because time-travel affects the person differently when the jump spans half a minute (like classical mechanics not being applicable for small objects). Maybe Jay has put in some settings into it to make it behave this way.
We only see it being used a couple of times besides this particular instance, why do we assume that this is how the device always works? I never really understood this attitude with all non-real tech in movies and books.
Out of the universe, there is no indication about how the device works because the film isnt centered on the time travel per se. In my opinion, you cant blame the director for not spending precious movie time to explain a small detail which doesnt affect the plot in a significant way. Its not really that important how Jay defeated Boris after all, it only matters that he did do that.
