[Somehow, Jean isn't surprised Reiner would cry about it. He's just mentally exhausted enough to not scoot over to hug him this time. It was also very different from the holiday party, where he saw Reiner cry last time. This was all different from that.

So instead he just keeps talking. He's good at talking.]

I won't say I'm glad I experienced that nightmare, because I'm not. But I am glad... that I can finally understand. Even if just a little bit.

[Perhaps he's talking too much, but he should probably get these things off his chest now that he has a chance.]

You know I will never forgive you for Marco, but I know now. The amount of pain you must have been back then and after. Even now, seeing him here probably brings the pain up sometimes. I know it does, because it happens to me, too, for different reasons.

[Majority of him was glad to see Marco. He was always glad to see him and that would never change. But sometimes he was hit with the cruel reminder that if they all someday went back home, Marco wouldn't be there.

Jean takes a deep breathe and wipes a stray tear that appeared in the corner of his eye. As if that would help prevent more of them.]
