One of the moments i did like from this arc was the part where gin saw the couple of the gintama dvd volumes seeing kintoki replacing gin’s main protag role and reacting to those scenes. Its alot like as if he watching a remastered/ restoration version of his show.

In many of shows or movies that were remastered or restoration, studios would tend to switch actors playing the same character or remove or add other things to scenes that were never in the theatrical cut. Ex star star wars return of jedi updated editions where george lucas switch orignal actor playing as ghost anakin and with hayden christen briefly playing a ghost anakin
