What should have been a run-of-the-mill charity banquet for Bruce and Damian has, quite literally, gone up in flames -- and now, without access to their costumes and gadgets, father and son find themselves fighting for their lives at the hands of the mysterious specter known only as Memento. But who is this new villain who set the blaze that threatens to disintegrate the Dynamic Duo, why does it replicate an infamous, century-old tragedy from Gotham's history, and what is Memento's connection to the Dark Knight's past? Nothing can prepare you for the answers to these questions, so join us and bear witness to "Memento," part two.
