David Harewood of Supergirl has an intriguing idea for an Arrowverse crossover event.

Every year, CW viewers look forward to the annual Arrowverse crossover events. The viewers aren’t the only ones who spend time thinking about team-up ideas. David Harewood, who plays J’onn J’onzz on Supergirl, revealed that he and the other actors sometimes come up with their own proposals. Speaking at a media event for Supergirl season 4 during San Diego Comic-Con, Harewood was asked if J’onn would ever trade super-parenting notes with Joe West from The Flash.

“Who knows? Maybe that’s another subject for a crossover let’s do it”, he answered. “Super dads”, I jokingly suggested. “The Super dads, yes I’d like to do that” David echoed. “Some of talking last night about doing a Black Lightning crossover where all the black characters come for Christmas dinner. I think that would be quite something”, David continued.

As of now, there are no plans for Black Lightning to crossover with the other Arrowverse shows. CW Head Mike Pedowitz hasn’t ruled out crossovers, and the showrunners (Salim and Mara Akil) have gone back and forth. While Black Lightning is filmed in Atlanta, the rest of the Arrowverse shows are filmed in Vancouver, which would make a crossover difficult. In addition to the “Super Dads” idea, David has also expressed interest in a Black Lightning crossover on Twitter.

David also had plenty to share with us about J’onn’s status quo in Supergirl season 4. “He’s walking the Earth. He’s living amongst the people in National City as he promised his father. But he’s really kind of struggling to live a life of total peace. When you’re as badass as J’onn, at some point you might have to step in and kick some butt. And I think that’s going to be his conflict going forward is how far he can take the idea of the pacifist ideals of his father and how he can really implement them in a world which is violent, and that needs to meet needs sorting out. So that’s something that’s going to be his conflict this year”, said David.

David also spoke about working with Carl Lumby and the powerful Alzheimer’s storyline in season 3. “Some of his colloquialisms were wonderful. I think the idea of watching your father slip away and repeat things, a number of people wrote to me and was saying how much they were moved by it because they themselves had experience of that. My own father died and had complications from dementia. So it was quite tough to play those scenes and you know I kind of told him about that. So every time we got together it was quite emotional. It was quite tough to do those scenes and wonderful to play with him. He was just awesome. Really great fun”, David told us.

I then asked David if it would be hard for him to see someone else leading the DEO. “I think he’s quite competent that Alex is the right person”, he said. “It’s very exciting for me because as I say, as a character I’ve never been outside the DEO. We’ve all only ever seen him in that DEO outfit. So it’s going to be interesting to see how he….you know we have to talk about how he dresses, we have to talk about where does he live what are his habits. So it’s like breaking a whole new character which is exciting. I think the audience is going to see him in a very different light this year. I think he’s trying to be peaceful”, David said.

A journalist at the press table asked David if we would be seeing more of his fatherly relationship with Alex and Kara. “Oh very much so. Yeah, I mean he’s never not going to be the father figure to Alex and Kara. And I think we see that in episode 404. There’s a wonderful sequence in 404 where I think he finally makes his mind up that he has to be the Martain Manhunter. And it’s a cool sequence. So look out for that”, David told us.

He was then asked if we’d ever see Miss Martain return to the show. “Sometimes a lot of these things do really depend on actors availability. And I think Sharon (Leal) is doing very well and I think she’s doing a show in New York so I’m not sure how much time she has off. But I’d love to working with her. I’d work with her again in a heartbeat. She’s a fabulous actress“.

Could a Super Dads crossover be on the cards for Black Lightning during Christmas 2019? Are you looking forward to seeing J’onn outside of the DEO? Supergirl season four premieres on Oct. 14 on the CW.
