The Force Awakens has already been analysed thousands of times since its release at the end of last year. Many easter eggs have been spotted and commented on.
However there is one that I have not seen mentioned or noticed before. We all know that Finn worked in janitorial services. This is a clear nod to another janitor from geek culture that has saved the universe on previous occasions.
This janitor is non other than Roger Wilco from Space Quest fame!!
