We present the holographic construction of the dark bubble model of dark
energy and highlight the pivotal role played by the non-normalizable modes.
Following the route of holographic renormalization, we show that the
non-normalizable modes are essential for having a vanishing mass for the
induced graviton in any braneworld model. We then apply this idea in the
computation of the propagator on the wall of the dark bubble introduced in
