We study the Page curve and the island rule for black holes evaporating intogravitating baths, with an eye towards establishing a connection with theER=EPR proposal. We consider several models of two entangled 2d black holes inJackiw-Teitelboim (JT) gravity with negative cosmological constant. The first,"doubled PSSY," model is one in which the black holes have end-of-the-world(ETW) branes with a flavour degree of freedom. We study highly entangled statesof this flavour degree of freedom and find an entanglement-inducedHawking-Page-like transition from a geometry with two disconnected black holesto one with a pair of black holes connected by a wormhole, thus realising theER = EPR proposal. The second model is a dynamical one in which the ETW branesdo not have internal degrees of freedom but the JT gravity is coupled to a 2dCFT, and we entangle the black holes by coupling the two CFTs at the $AdS$boundary and evolving for a long time. We study the entanglement entropybetween the two black holes and find that the story is substantially similar tothat with a non-gravitating thermal bath. In the third model, we couple the twoends of a two-sided eternal black hole and evolve for a long time. Finally, wediscuss the possibility of a Hawking-Page-like transition induced by real-timeevolution that realises the ER = EPR proposal in this dynamical setting.
