Semblance

Definition of Semblance:
The state of being somewhat like something but not truly or fully the same thing.

With the Pines family tricked, and wary of each other, Bill Cipher puts together a plan to merge Reality with the dreaded Nightmare Realm using the Rift.
However, things don't go exactly as planned.
