[ The end result is still the same, just as Kyoko is saying. Their world as they knew it has been destroyed by now. There's no doubt about that in Madoka's mind - and given what she heard from Homura and Kyubey before ending up on the train, she thinks that just her disappearing from that world might have screwed it up in a major way on top of that, given how the timeline had wound up around her..

It makes Madoka go quiet again. All of this is so hard to think about, let alone talk about. It makes it feel like there's an empty pit opening up somewhere inside of her. ]

I tried.. so long to hold onto hope.

[ She really did. Even when it was hard, she still wanted to do so. ]

But on this train, with everything we're hearing.. It's like there's less and less of that left. I don't know if there's even anything left to hope for at all.. [ Because, sure, Madoka is still alive like this. If she wouldn't return home, she could just live like this instead. Here on the train.

But it doesn't feel worth it if her entire world, her family and friends included, had to die off for that. Madoka can't live with that thought. ]
