How did you feel about Jefferson's decision to retire at the end?
Well, I tweaked it just lightly. A bit of an inside story: The original piece of dialogue said that I full-on retire. I don't know if any of these things are going to come to fruition, so they're not set in stone, but I have had people from The Flash reach out, asking if I'd come do some work with them. So they had kind of tentatively reached out months before we shot the finale. So in anticipating me leaving that door open, and anticipation of that being a possibility, that's why I changed it slightly to basically say, "I'm done in Freeland and just kind of like giving Freeland over to my daughter." So that if I show up somewhere else, I haven't contradicted anything.
It's funny, I was going to ask you if you were opening to returning as this character on one of the remaining shows. It sounds like you are?
We're moving back to California, and so Vancouver, for short stints, to pop in and do something and pop back out, is not as challenging for me and it doesn't require packing up and moving my whole family. I wouldn't be able to suddenly join another show that's not in California. So there's that logistical thing. But also, you know, I really enjoyed the crossover last year. Specifically, I think me and Grant [Gustin], we're just very like-minded in how we approach the work, and we had really great conversations. One of my favorite scenes of doing this character was the scene between me and him in the library [on the Waverider in "Crisis on Infinite Earths."] So the thought of being able to go back and do an episode here or an episode there? Oh yeah, no, I'm down for that.
Is this anything confirmed yet, or are you still in the talks phase with The Flash?
Just in the talk phase. I was really surprised because it was months ago, I think in the fall, when they first approached me about, "Hey, do you, would you do something with us next season?" And so I initially said yeah, or my representatives said, "Yeah, we're interested, but you know, that's quite a ways away, and who knows where we're going to be at that point." And they just kind of came back saying, "Hey, we'll work around your schedule. We just want to know if you're interested."
Then probably about two months ago, they came back with like, checking again and saying, "We're thinking about a couple of episodes, and these are the months that we're thinking about, and want to just, again, see if you're into it." And basically we said the same thing, like, "Yeah, yeah." So I imagine at some point the next thing will be something a little bit more final.

♦ The Flash‘s five-episode event will feature crossovers with TBD Arrowverse characters. “We’re talking about other superheroes from the CWverse that will come together in each [of the] individual episodes,” says CW CEO Mark Pedowitz. “That will not quite be a crossover but it will have a crossover-type feel at the introduction of all these characters.”
Here's Deadline's report on the five episode Flash event featuring other Arrowverse heroes.It will be in November.

This fall, the CW is bringing together for the first time on the same night its signature, most streamed series, The Flash and Riverdale. Both series will start their new seasons (S8 for The Flash, S6 for Riverdale) with special five-episode events, which will kick off in November, about a month after the CW starts rolling out its fall lineup in October.
During a press call about the fall 2021 schedule on Tuesday, the CW chairman and CEO Mark Pedowitz noted that event-izing applies specifically to The Flash, whose first five episodes next season “will feature different heroes from the CWverse.”
“The idea for The Flash is, (showrunner) Eric Wallace and (executive producer) Greg (Berlanti) have come together and are talking about other superheroes from the CW-verse who will come together in each individual episode,” he said. “It will not be quite be a crossover but will have a crossover-type feel and the introduction of all these characters.”
Pedowitz spoke about the logistical challenge faced by The Flash and Riverdale, whose current seasons stretch deep into the summer on the CW schedule. The shows will complete production on their current seasons in late June-early July and will go on hiatus until returning to start filming their new seasons in early September “fully rested,” Pedowitz said.
Because of the late start, neither show would be able to deliver the eight or so originals that usually air in the fall, leading to the CW’s idea to event-ize their five-episode fall runs.
Warming up the night for The Flash and Riverdale will be the final season of Supergirl and Season 2 of Stargirl, which will premiere in August and will run on Tuesdays through October, leading to The Flash and Riverdale‘s return.
So it sounds like Flash Season 8 will premiere in November with this five episode crossover Flash event after Stsrgirl Season 2/Supergirl Season 6 wraps airing.
I wouldn't be surprised if this is where Cress Williams will appear.And I won't lie,it would be so great if Melissa appears in it and other Supergirl characters.Almost like a final farwell to her fellow Arrowverse heroes.

Here's EW report on the Flash five episode crossover event.

A new detail is in it.
Pedowitz didn't say which actors would visit The Flash in November. "I'll let you have those conversations with Eric Wallace," Pedowitz told EW on the call. "We do know that there are a couple feelers out to a couple of the actors, but we have no definitives yet."
One of which,is Cress Williams it seems.
