The Puppet does appear in FNAF: Security Breach as an easter egg – upon closer inspection, its mask can be clearly seen on the Blob's figure. The Blob, while being the secret antagonist, is a nest of east eggs as it is the amalgamation of old, salvaged animatronic parts.  That is not to say that the Puppet itself is somehow a part of the animatronic's conscience. That's because Charlotte moved on long ago, as is evident from the absence of tears on the Puppet's mask. A neat little detail indicates that Charlotte was no longer a vengeful spirit, having settled the score with her murderer decades ago.
