Jensen Ackles isn't mentioned in the article, but all the pics in the slideshow have him in it as his twin characters Ben and Alec McDowell and two of them don't even have Jessica Alba/Max Guevara in them (#1, 2, 3 and 5 are Alec, #4 is Ben). They were probably mined from social media; most Dark Angel pics on Tumblr are Jensen pics.

"Clarke has not appeared in the franchise again"

I was going to say this wasn't completely true because Qi'ra appeared in an episode of Star Wars: Forces of Destiny ("Triplecross"), but I checked IMDB and apparently she was voiced by Olivia Hack instead of Emilia Clarke in that episode. At least it was Emilia's image used as the basis for her animated appearance.

Even if it was Eric's original intention that Ben wasn't Dean's son, other showrunners could do that they wished with it.

Having a realistic amount of illegitimate children from Dean's one-night stands must be one of the real life consequences Chuck protected them from... 🙄

"However, Supernatural does not have some gimmick that makes it a never ending story." Yes, it does: the brothers could have just driven off together at the end with the implication they're still out there working various cases. Then the finale's title, "Carry On", would have been accurate. That's how it should have ended, instead of the finale's maniacal need to cut off loose ends and make any continuation impossible by killing Dean and aging Sam to death.

The Winchesters was a great show which I honestly enjoyed more than the later seasons of the parent show, and it's a pity that so many people decided they didn't like the premise and didn't check it out. It had a Scooby Gang atmosphere more reminiscent of Buffy. I don't think the people who didn't check it out but want a Supernatural reboot/continuation quite fathomed that the cancellation of The Winchesters gives The Powers That Be the false idea that it failed because there's not enough enthusiasm for Supernatural, thus making it less likely they will greenlight a Supernatural reboot/continuation.
