We show how the traversable wormhole induced by a double-trace deformation of the thermofield double state can be understood as a modular inclusion 
of the algebras of exterior operators. The effect of this deformation is the creation of a new region of spacetime deep in the bulk, corresponding to a non-trivial 
center between the left and right algebras. This set-up provides a precise framework for investigating how black hole interiors are encoded in the CFT. In particular, 
we use modular theory to demonstrate that state dependence is an inevitable feature of any attempt to represent operators behind the horizon. Building on this 
geometrical structure, we propose that modular inclusions may provide a more precise means of investigating the nascent relationship between entanglement and 
geometry in the context of the emergent spacetime paradigm.
