User blog:Martialmaniac/How will Gon regain his Nen?

While I still don't believe we'll ever get to read a proper arc, I'd like to discuss this. I have come up with a few hypotheses, though there are many I don't like.

0- Gon will never be able to use aura again:

Instead, he will focus on honing his body and combat skills. Or he might use the Nen runes to simulate the effects of aura.

1- Killua asks Nanika to grant him one last wish:

Killua told Nanika not to use her powers again, but she migh tmake an exception for him; however, her power might not work in this specific case, seeing that Gon cannot use his aura after having been healed.

2- Gon trains again:

Ging stated that Gon "has gone back to normal". It is possible that Gon's aura nodes have been closed, and he merely needs to learn how to open them, either by forcing them open like Wing did, or by learning it through meditation. In this case, will he still have the same talent as before? WIll his amount of aura and aura output go back to how they were at the beginning?

3- Gon modifies the conditions of his Vow:

I'm not really sure, but it could be what Kurapika has doen with his Judgement Chain.

4- Someone or something in the Dark Continent lifts his restriction:

It does not need to be a friend: for example, there might be some creature able to completely cancel the effects of Nen around it, and in attacking Gon, it removes his curse.

5- Someone in the known world lifts his restriction

6- Something else (please, state in comments) Which will it be? Theory 0 Theory 1 Theory 2 Theory 3 Theory 4 Theory 5 Theory 6
