Little Jumper Chapter 49 Discussion

So Narusawa is Chima's real father..

1. How did she somehow know he's her father? From the way she's acting, it's implied that she knew it from the start that Hiroki is not her father? Or did she realize after seeing the Albert Einstein photo? (I somehow this mentioned by her). Even if she did somehow realize that Narusawa is her father, I still can't understand how she can come into that conclusion with just a little bit of hint?

2. Ai told Hiroki that she somehow got pregnant at the first time travel. Did it mean she got pregnant by Narusawa before time travelling? Why did she not tell Hiroki that he's not Chima's father?

3. Hiroki was told that he will die(again) in year 0041, how did Shiratori knew that he will die? Ai also get healthy again, she'll not get healthy until the 0041's Hiroki alter the Ai's recovery point. So does this mean it's not the second loop of time travel?

4. They did say the rebuilts are immortal, does this mean Ai too? She seems to aged a bit(even though she's supposed to reset?) while Chima and Ichinose don't change 17 years later. If they're indeed immortal, I hope that Ai and Narusawa will meet again 100 years later.

Overall it's an excellent read, the author handled the time travel story and characters very good.

Btw, looking at past discussions, many people were fooled into thinking Chima was her own mother and having genetic mutation because of incest :)
