In the brawl, Tobias tumbled out of the window and got impaled on a spire.
But that doesn’t mean he’s retiring from the superhero business completely.

ENTERTAINMENT WEEKLY: The final season put Jefferson through the wringer.
How did it feel to take Jefferson to such a dark place this season?
CRESS WILLIAMS:The biggest thing is that it just felt appropriate, you know?
When we started the season, we didn’t know for sure that it was our last season.
But yeah, I just felt like it’s a fitting end.
Did you find it challenging playing Jefferson in this headspace?
Oddly enough, I didn’t.
I just felt so rusty.
And I was like, “Wow, I really suck.”
From day one, scene one, of this season, I remember feeling no rush whatsoever.
What was your reaction when you read the finale script for the first time?
I just thought it was appropriate.
I like the fact that the family gets their happy ending.
I’ll admit, I was surprised that Jefferson actually killed Tobias after avoiding it for so long.
I was surprised too.
It’s like, “Well, no, that’s clear.”
Black Lightningpurposefully kept Jefferson and Tobias apart for most of its run.
How did it feel to finally reach this long-awaited confrontation?
I can say from a work standpoint it was a lot.
And normally fight scenes don’t take that long.
They scrambled and found another one.
And then he immediately went down with a dislocated knee.
We were trying to troubleshoot why they weren’t working, and it was taking lots of time.
And it was a day that just felt like, “Wow, are we under a curse?”
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.
So they had kind of tentatively reached out months before we shot the finale.
So that if I show up somewhere else, I haven’t contradicted anything.
It sounds like you are?
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 thecrossover last year.
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 withThe Flash?
Just in the talk phase.
And they just kind of came back saying, “Hey, we’ll work around your schedule.
We just want to know if you’re interested.”
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.
What do you remember from your last day on set?
In the end, he gives me the inspiration that I need to break out and survive.
It was so simple.
Again, it felt really easy.
And it was really cool, it was fitting.
The biggest takeaway I think will be this is now a part of history.
I’m most proud of that.
And they really would love to meet you."
They’re like, “Does Black Lightning live here?”
And I came up and it was two little white boys.
And I was just like, “Whoa, hey.”
So things like that were really surprising.
I remember talking about sci-fi with James Remar.
Actually, James and I just had so many conversations, and he’s knowledgeable.
I think those are the things I’ll miss the most.
