It *MIGHT* mean Rogi and Tora won't be together. But I do believe they will be on good term again.
That's the one you're reading right here...?
Oops, my apologies for not refreshing the page before I posted this. I hate it when other people tell me redundant things, I hate it even more when I do it to someone else!
Although it is interesting to note how this chapter kind of parallels Rogi and Hachi's first meeting!
At this point, I think it's going to be clear as day, Akitora is NOT going to get back together with Rogi what so ever, even in the future. There is something in this story that will reveal as to why Akitora broke all ties with him in the first place. And after Rogi sodomized his son, I don't think Akitora would feel comfortable dating Rogi after that, even if Tatsu brushes off the events.
I also don't think Akitora and Rogi will get back together but I think there will be a different reason revealed and it will have little to nothing to do with what Rogi did to Tatsuyuki. We are learning a lot about Akitora, primarily that he is drawn to people who he thinks mirror him or display qualities he thinks he possesses. He uses people to feed his ego. If he still found Rogi complimentary to his ego, what Rogi did to Tatsuyuki wouldn't stop him from taking up with him again. After all, he knew who Rogi was and what kind of person he was and yet he allowed Tatsuyuki to be indebted to him without intervening.

He allowed Tatsuyuki to bring Rogi into the organization even after knowing what had happened. And we're witnessing right now that Akitora is self-involved and self-indulgent, regardless of the feelings of others. So I don't see Tatsuyuki's rape getting in the way of anything Akitora wants.

Do you guys remember the manga's name about rogi and other boy (not akitora's son)?? I just can't remeber and can't find anywhere!!!
