When Biscuit tells Killua that if he shall fail the battle with Shoot, he must leave Gon. But Killua did fail the battle and and he stayed with Gon past the battle and then the 30 days. Why is that? Why did Killua stay with Gon?

this is about how mush time KURAPIKA lost from his own life . we know that using THE ABILITY for one second cost one hour from his life the first time KURAPIKA used EMPEROR TIME was against UVO and he used his EMPEROR TIME from the beginning so he used it in the first part for 455 seconds and after the flashback KURAPIKA used it again for 309 seconds which is 764 seconds and 764 hours was taken from his life and thats 31 days and 19.92 hours and then in the manga if u didnt read the manga then stop reading the post . anyway he used STEALING CHAIN on SAYIRD and used EMPEROR TIME for 3 hours and passed out for 9 hours which is 12 hours in total or 432000 seconds so 432000 hours were taken again from his life or u could simply say 4.93150685 years and to mix both times we put together 4.93150685 and 31 days and 19.92 hours which is 0.00971004498 and in total KURAPIKA lost 4.94121689498 years OR 4.9 YEARS THATS MORE SIMPLE

But can someone do the math and figure out exactly how many years Kurapika has lost due to emperor time? I probably don't wanna know but I feel like it is a question that should be answered.

What? If pitou spare  gon, what do you think will happen to him or her after realizing that the king is dead and so the Royal Guards, what do you think what happened to pitou, pretty much I just want to hear in like a what if story for pitou?
