[The letter mentions that, and that there were somethings Grimm wouldn't write down about Ekkehardt because it should be his choice to talk about those things. He can pick up on the air of mystery around this person - he really doesn't look like a healer - but there's still that nostalgic feeling.

A feeling that seems to be right.]

I met him a little bit here, in this darkness. [It was strange to see, a future (a past?) he'd never experience. A disconnect.] He seems like the kind of guy who'd make life hard for a friend and laugh. In a nice but really weird way.

[Grimm had no reason to let people see Alderic and it wasn't hard at all to accept this was his fate. He could have left pretty much within minutes of meeting. But he didn't.

A choice to let Alderic exist a little longer. And the desire to let people make those choices still resonates within them.]

But I guess knowing a little about you means I can get to know you again. I-if you want.

[Alderic and Grimm are not the same person. And it sounds like Ekkehardt was really fond of Grimm. He couldn't give that back.]
