Road to Broadhurst

I am going to soon run "Road to Broadhurst" For two new players and I am worries they are going to die, since Draw Steel was playtestet at around 3-5 players. To make the players survive I am think adding a retainer, so they have an additional buddy and I can indiretcly teach them the rulls. Is addaing a retainer enough? Or should I do something else to make them survive?
