Having to fill so many speaking roles, the showrunners not only "postponed" the introduction of several key characters, but they also merged some into one, or certain plot-functions were given to different characters.
For ikke at skulle udfylde så mange talende roller, havde showrunners "udskudt" indførelsen af flere centrale figurer, men de har også slået nogle karakterer sammen i en, eller bestemte plot-funktioner blev givet til forskellige karakterer.
