it all makes sense now.
I was getting SO confused between sachiko/satsuki... but now they explained that ren named her....
wait so baby ren is also hachi and takumi's kid? somehow i didn't really get that... or think that. i mean sure they said "nana will want to take him back" but it still could be the child of reira and takumi, but hachi takes care of him sort of deal.
though, thats probably me being stubborn... since i dont want hachi and takumi to have a sucessful marriage. i'm still rooting for hachi and nobu.... and i WILL be dissappointed if it doesnt end that way XD
I am almost positive now that ren dies. because all those times hachi asked "hows ren doing" on the phone to takumi, she was reffering to baby ren. And why give baby ren that name ? it only makes sense if ren dies. And with this drug problem he has, and the fact he's quitting trapnest, it all just seems to be coming together. I have a feeling he will die from drug overdose, like Sid Vicious (sex pistols) did... but knowing ai yazawa she'll probably be a little more creative :3
Theres still some stuff that needs explanation, but for the most part i feel like i see where this is heading.
edit: interesting little theory i read on a different site. Maybe Satsuki is actually nana's child. Hachi wont leave tokyo to be with takumi because she's waiting for nana to come back to her and satsuki. If they found nana, then hachi would have a reason to go to london. Though there are so many ways to counter this theory i thought it was an interesting point :P
