Troubles utilizes a cast of three people, two playing all of the other roles as Gerry is the main character and has a dedicated actor. There is limited description regarding how the actors switch in and out of character, other than the information provided on the character’s descriptions in the initial blocking. Did you expect people to exchange costumes or hats to identify them, if scenes get very crowded, much like the two ensemble characters in The 39 Steps?
Also, in his Romeo and Juliet play, he based the play on an actual marriage between a Catholic and Protestant, describing them taking a bus to the two homes and then going to the church, seeing the ceremony, and then both parties leaving on their buses. I was curious as to what church-Catholic or Protestant-did they get married in?
