The CW’s DC dramas are all in the home stretch, as Supergirl, Flash and Arrow race toward their respective finales next week. Supergirl and Arrow at least get extended trailers for their final outings (Flash has a few spoilers to protect), and there might even be a minor tweak for this fall’s crossovers in store.

First up, Monday will see Supergirl squaring off with Superman for Season 2 finale “Nevertheless, She Persisted,” the extended trailer of which lies above. You can also check out the full photo set, while Arrow Season 5 has its own extended trailer, complete with a number of past returns. Hello, Captain Boomerang!

As if that weren’t enough, The CW’s recent Upfront presentation saw network head Mark Pedowitz noting that the four-way crossover is set to air in November. Granted, the first two-thirds of 2016’s “Invasion!” crossover aired in November’s final days, the prior crossovers have all aired in early December.

Complicating matters somewhat is that The CW’s fall 2017 schedule makes for an unusual airing. Supergirl remains on Mondays, while Flash and Legends of Tomorrow are now paired on Tuesdays, with Arrow jumping from Wednesday to Thursdays at 9:00 P.M. That could theoretically set the crossover dates for November 27, 28 and 30, unless the event has been moved earlier in November to allow each series more time to set up winter finales.

We’ll see if next week’s closers paint any clearer portrait of the four-way crossover (and remember, Black Lightning is keeping separate), but stay tuned for the latest in the meantime.
