Honestly for them to meet is pretty simple in my opinion.This can happen many ways.Either they both was gambling in a tournament and they meet there or Toji was in said tournament for cash,as he would be broke, and Tyrion saw him and wanted him in his house service.They can meet when he joins the group that Catelyn use to kidnap Tyrion and Toji was in the tavern at the time(must likely the plot for the first chapter).Or Toji does his thing and just eventually finds himself with the Lannisters as they have the most gold after making a name for himself again.Honestly Toji can be with anyone as his motivation is pretty simple;follow the money.Toji can seek the Lannisters for employment and Tyrion was just the easiest one to find,get too, and get along with.I think this will be a fun idea and it will interesting to see how people handle Toji.Toji can’t be everywhere at once nor can he be active all the time so he can moved around.
