While the above answer is all well and good, I still think it seems a little much to include Constantine in this wikia. This is a one-off event. The Simpsons and Family Guy wikias have not been join together because of their crossover. Boston Legal had a character appear from Boston Public, they’ve been kept separate. I highly doubt Bones and Sleepy Hollow will have their wikias combined when those shows crossover. NCIS-LA with Hawaii Five-0. I could go on and on....

This is A Detective Munch situation. Richard Belzer has played his Law and Order character on shows like The X-Files, Arrested Development and The Wire. Matt Ryan is in the same boat. He's a character from another show appearing as a one-off. It's just a wink to the audience. Nothing more.

To change this entire wikia is a waste and unnecessary. Constantine the series is not set in the same world as Arrow et al. Flash/Arrow/Legends/Vixen are all part of the same universe and has been planned as such. They're by the same creative team. Constantine is by completely different people.

Finally, even the article used as proof can be seen as ambiguously written as we don't know the direct question asked of Mericle and what the author added afterwards. Similarly, Mericle could have misunderstood the question.

I think it would be best to remove Constantine the series from this wikia.
