You can't blame yourself for how you feel... you know you can't help it. Being jealous of them doesn't mean you aren't happy for them, too. That you don't love them and want them to be happy. But you've gone through so much, yourself... of course you'd see them and think about what it could be like for you.

... I'm jealous of them, too, sometimes. [Shrugs, looking down] Or, more that I'm jealous of Neal and Emma. [To have parents who love them so much that they'd do anything to get to them again. That they all survived and have each other, despite all the other losses in their lives.] I know it wasn't easy for any of them - but I can't help but feel it sometimes. You wouldn't blame me for that, would you?
