NO, diesel didnt say anything about Ein, they talked about trust and yanek call diesel dog and because he is a dog he have to be loyalty to him and die for him, yanek say something about he doesnt trust people and he think diesel was aware about Ein identify and keep the secret from him, diesel say something like if he doesnt trust people with that way of think why he will trust him!
Anyway diesel go to ein to give it a warned about yanek, he will try to killin him if he show he face to yanek, Ein for some reason said, that he wanted to find out something about Diesel earlier and send him back (to his homeland, I guess), but, well, “Diesel” is not even his real name. Ein said that he still can’t believe even his own memories and asked if Diesel just came to warn him or wanted to deal with an obstacle himself. Diesel agreed, that he’s thinking about it, but Ein pointed out, that his shoulder is injured and he probably won’t be able to win. Besides he said, it might be better to get rid of someone, who doesn’t even have identity and continue with the mission, so they start fighting...
I think the past of Ein is more dark that diesel, the mention he says about he doesnt believe even in his own memories it made me think......

Thank you so much!
Wow, so much is going on in this chapter! The story is really getting intense! Diesel really did try to save both, but we know in the end it is for naught. I honestly can't say I am surprised that Yanek basically views Diesel like that...I've been saying it since the beginning that he views him more as a dog and unfortunately it seems to be true. And what he said is beyond messed up.
Yes, I also think that Ein has a dark past too...I really hope the author goes into his past as well.
Spoiler chapter 53
Dialogue between Yanek and Diesel happens, I think he tells Yanek everything and Yanek tells Diesel to kill Ein (not sure about this)
The scene in chapter 20 happens again. Turns out than Diesel goes there to attack Ein at the fish market.
Ein and Diesel get into a heated knife fight, and Ein has Diesel pinned up against the wall with the knife pressed against his chest.
