Seems Iori has picked up some of Koushiro's habits.
I totally headcanon that Iori picks up Koushiro's bad habit of spending hours and hours working to the point where he's basically dead because he needs to find to do something, he needs to prove he's a good defense attorney just like Koushiro overworked himself to find a solution to the reboot because he was the smart one and that's what he does, find solutions to problems.
Bonus headcanon: Takeru's the only one that can really snap them out of their work and their own self malice. Also get them to take a break and get some much needed rest
