When "Constantine" was cancelled on NBC in 2015, fans of the series were left wondering if the series would be picked up by another network for a potential season 2.

Now that the "Constantine" season 1 is already being streamed on The CW Seed, talks about the renewal has surfaced once again, with some fans speculating that a season 2 will follow the current series. Some also speculate that John Constantine, played by Matt Ryan, will appear on "Legends of Tomorrow."

Right now, all the 13 episodes of "Constantine" are being streamed on The CW Seed. The episodes started airing in early July, and fans who missed the early episodes are free to re-watch.

Despite this privilege, some are still curious as to why the series is being streamed on the site after being off the air for more than a year. It may be recalled that NBC pulled the series in February last year due to low ratings.

Following the show's cancellation, Constantine has appeared on "Arrow." Some believe that since it was made possible on TV, there is a huge potential for a "Constantine" revival.

There are also speculations that The CW is now in the process of testing if the first season will be well-patronized. Fans also speculate that if the show will not be renewed for another season, then the character may just return to "Arrow" or become part of "Legends of Tomorrow."

While The CW has not made any confirmation regarding "Constantine" season 2, fans are free to enjoy the rerun of the first season on the CW Seed website.
