Is it really all that risky, I mean we all have known that all the girls would get a happy ending, it would be a harem ending so really having their children end up back in time, doesn't really ruin the ending, since we all expected that he would have children with at least some of them.

Also I can't rap my head around the speculation with Gabriel and Serafall being with Issei zero interactions with each other, except maybe saying hi, and yet people speculate that they will be included in the harem. Maybe I just missed something.

Honestly speaking Goristie sounds more likely then the other two to be in Issei's harem. Besides monkey + Dragon= Insane character design and abilities.
