Whats great about The CWs DC shows is how they reward you for paying attention to whats gone on before. Thatd be continuity, kids! It sounds a simple premise, but so often certain other shows seemingly forget their own previous storylines and plot points. In a nice nod to The Flashs first season, here we see Jax remember hearing about a trick Ronnie Raymond and Martin Stein used when Stein was holed up under the shackles of General Eiling. The trick here is that if Jax carves a message into his body, it appears on Steins. As such, Jefferson gets Kendra to pen some reassurance on his arm so that Stein knows that theyre on their way.
