Okay here are answer to questions.
1). Stress focus
Basically training. And denial. He was stressed but he had to work the problem. It took him about 20 minutes to figure out that it wasn’t an instrumentation failure. And once he made the decision to send them to the LM then relief.
2) comsumables. About 10 hours
3) contingencies. Many. A couple was that they installed a battery on the command module also they put an extra oxygen tank on the other side of the module.
4) emergency training. He said there was extensive training that was different but he didn’t get into it with me.
5) other mission crapping out. Nothing like 13. There was one where a fuel cell failed but it wasn’t a big deal.
