Like the universe we inhabit, the DC television universe expands beyond its Defined Constraints.  Instead of just the CW, we are now branched out to Syfy and to CW Seed.  While a decent chunk of our heroes enjoy their vacation, Lucifer takes a back seat to C̵l̵a̵r̵k̵ ̵K̵e̵n̵t̵ Pierce, Legends has the best pun of a show title yet, while Black Lightning enjoys some quality time with the family.  Out in deep space, Krypton begins to end, and we get a heaping helping of John Constantine.
