I believe he is going to be able to go back and forth from limbo

^interesting theory, I didnt think of that

At first I thought that it could be because of Malivore too. But then Kaleb isn't getting sick at all. So I don't think it has to do with Malivore. Maybe it has to do with Ken maybe he cursed Ethan.

Well the thing is we dont know for sure what species he is, it has just been assumed he is part pukwudjie

I just think he is having problem controlling the powers due to the current stress of Gods. We will get more info in the next episode anyway.

Yep

I think the powers are unstable and not compatible with a human so only way for Ethan to live would be for him to return to being human.

They should have ethan put his power to good use if he is not long for this earth and put his hand inside ken and just tear his heart out

Not sure he is capable of doing that and that would require a certain ruthlessness that Ethan does not have.

Well we wont know till he tries
