What do you mean by "stuff going on with them"? Because I've told you that they don't ever talk about their pasts or even general emoting states at any single time.
I seem to remember Oda writing in an sbs that they do talk about personal stuff, but its off screen. Which I find a bit of a cop out.
It seems you are forgetting a lot of shit dawg. Most of the actual interactions they had were them talking about the plot or goofing off or making plans or commenting about something they've witnessed.
