Legends of Tomorrow's Letscher Teases Reverse Flash's Plan, Cold's Return

In the mid-season finale of "DC's Legends of Tomorrow," Reverse Flash finally let his cohorts Damien Darhk and Malcolm Merlyn in on what he was searching for: the Spear of Destiny, which has the ability to alter reality itself. However, the episode was less clear on Reverse Flash's end goal once he has it. According to Matt Letscher, who plays Eobard Thawne himself, we're going to find out what Reverse Flash wants in "The Legion of Doom."

Speaking to CBR, Letscher teased Reverse Flash's plan, and he promised that Thawne's motivation would be "a major reveal" in the next episode of "Legends of Tomorrow." Letscher also discussed the Legion's dynamic, the upcoming return of Leonard "Captain Cold" Snart, Thawne's important "foreknowledge" of events and more.

CBR: So I spoke with Marc Guggenheim last week, and he mentioned that we'd find out what Eobard Thawne wants with the Spear in this upcoming episode. What can you tell us about that?

Matt Letscher: I can tell you that we find out what Eobard Thawne wants with the Spear in this upcoming episode. Yeah, I can't tell you much more specifically, but I will say that a lot of what the episode deals with is just how well the Legion of Doom is working together -- or how well they're not working together, I should say -- and it sort of helps sort out the relationships and how they're going to move forward from this point. A lot of that has to do with why Eobard needs the Spear of Destiny so badly.

Next week's episode is titled "The Legion of Doom." Does this mean we're going to learn more about Thawne's team and why he chose Malcolm Merlyn and Damien Darhk?

You'll learn a little bit more about that for sure. Yes. The answer to that is yes -- the short answer. The larger piece of the episode is Darhk and Merlyn discovering what it is that's driving Eobard, because he's kind of been hiding that information from them. It reaches a boiling point in this episode, you know? So there's kind of a major reveal in terms of what's motivating Eobard.

The synopsis for next week's episode says Thawne will pit Merlyn and Darhk against each other. Will we see some in-fighting between the three of them in upcoming episodes?

Oh yeah! Yes. There's going to be torture, there's going to be combat, there's going to be psychological warfare. It's definitely a big hashing out of differences between all three of them, but it does resolve with a greater sense of unity and urgency at the end of the episode, and we definitely get a clearer sense of where the team is going in the second half of the season.

Are we going to find out what Thawne has been up to between "Flashpoint" and "Legends?"

Yes, to a certain extent. Again, a lot of it has to do with what's motivating him. It is definitely the same guy, and what he's doing in the "Legends"-verse is very much tied to what has happened to him in the "Flash"-verse. A lot of those threads are pulled together in this episode.

Jumping off that, are we going to see how he found out about the Spear of Destiny?

No. You just to assume that his intellect, being from the 22nd century, that his intellect and knowledge far surpass anybody else in this realm. He just knows. He knows he needs it, he knows how to get it and it's just a matter of executing it.

Thawne and Rip Hunter are from approximately the same time period, give or take a few years, and they're both into time travel. Were they aware of each other prior to their involvement in "Legends" and "Flash?"

That's a good question! I don't know that. I don't have any definitive information when it comes to that, but I will say it strikes me that Eobard always speaks of Rip Hunter with great respect over the course of the series. That may be some sort of hint as to, if not a personal relationship, at least some foreknowledge of Eobard's part about the type of person Rip is and the time that he's from.

Seeing as he's from a future where time travel is possible, is Thawne familiar with Rip's condition?

A lot of that is discovered in this episode. They do a lot of work to sort of track down all the details of how Rip came to be this way, but I will say that Eobard possesses a lot of knowledge necessary to sort through the clues in this episode. He's definitely the one who figures out how Rip came to be where he is now and leads the way towards unlocking his secrets.

Can you tease anything about the arrival of Captain Cold?

Well, I can't tease too much, other than to say he's definitely on his way. He's going to be here shortly, in the next few episodes. He is going to be a full-fledged member of the Legion of Doom and be very valuable to them on multiple fronts. Eobard has done his homework in this regard, and he's recruited somebody who's fully on board with the Legion of Doom's mission and he also understands the complications that Captain Cold's relationship with the Legends… the psychological complications that inform Eobard and his plans. That's probably about all I can tease, but it's really fun!

Thawne just recently learned about the time aberration that is Martin Stein's daughter. How does that factor into the back half of Season 2?

That will come up again. I can't say that I've seen it factor in yet a whole lot, so far as Thawne and the whole Legion is concerned, but it definitely is something that presents itself again.

Now that you've been on "Legends" for a good number of episodes, can you talk a little about what it's been like to transition from one "Arrow"-verse show to another?

It's been really fun! "The Flash" and "Legends" are two very different shows, even though they're part of the same DC world. "The Flash" is definitely -- in my mind, anyway -- a much more intimate, kind of family sort of show and "Legends" has transformed itself into this sort of big, bawdy, adventurous, chaotic miasma of colorful characters and time travel. To go from what feels like a smaller, more intimate world to a more unpredictable, wide-open world is really fun. Then, to get to play with other baddies, other great actors -- I just called myself a great actor, didn't I? [laughs] I mean other actors that I respect, like John Barrowman and Neal McDonough. That's always fun, because bad guys tend to work alone, so there's a lot of solo screen time. It's nice to have some pals.

And finally, a very superficial question: do you prefer wearing the black leather jacket or the full Reverse Flash ensemble?

I prefer the full Reverse Flash ensemble, because it gives you the most badass feeling to have it on. When you actually get yourself into that suit, which is a complicated process, you don't necessarily feel super comfortable in it, but there's something about it that -- once it's on -- you just feel badass. The black leather look is fun, for sure, but -- if I'd rather -- it'd be the suit.
