It was revealed during The 100's Comic-Con panel today that Lexa (Alycia Debnam-Carey) -- last seen betraying Eliza Taylor's Clarke by taking her fighting Grounders out of Season 2's final battle -- will definitely return for some fierce Season 3 drama.

When a fan in the audience asked a question about whether or not there'd ever be a reconciliation between Lexa and Clarke, showrunner Jason Rothenberg answered, "I suppose there’s hope for reconciliation because Alycia Debnam-Carey is coming back to the show. And, yes, Clarke is pissed and there’ll be fireworks between them that we’ve never seen before. I think that it'll be interesting to see how they butt heads. Or not.""They will make an attempt at peace, for sure, but there's a lot of bad blood," he continued. "When we start off in Season 3, the war is not on and the tensions have been released slightly, but that won’t last very long."The big issue with Alycia Debnam-Carey returning was always due to her being cast on AMC's Fear the Walking Dead. But Rothenberg addressed that. "AMC was awesome in terms of the negotiation and scheduling and it was great because we still had a story we really wanted to tell. We’re really going to dive deep into the Grounder clans and their mysticism and origins and that character lets us do that in a big way."More news regarding Season 3, which kicks off production very soon: There will be a little bit of a time jump. "We are going to have our first time jump between seasons," Rothenberg said. "We pick up a couple of months after Clarke bailed on everyone and Season 3 will be and feel as different from Season 2 as Season 2 felt from Season 1."Rothenberg then spoke about how Season 3 will get back into harder sci-fi with the new Jaha arc. "The A.L.I.E. story, the A.I. story really sets us up in a new more science fiction direction. You know, Season 1 had a very hard sci-fi aspect to it, being set out in space, and then everything got sort of grounded, literally, in Season 2. So I'm excited to get back to doing more sci-fi things on the show."Rothenberg then addressed the show's overall darkness and grim subject matter. "The world is a tough world that these characters have all found themselves in," he said. "And we’re just trying to be honest to that world. They’ll find some hope with each other. They’ll fall in love or fall in 'like' or fall into bed. The same way we try to find bright spots in our own lives. I get it. I feel like the show is dark. It’s going to be dark. It’s not going to change. Little things like Lexa and Clarke’s relationship - or 'Bellarke' if that’s ever going to happen - will be our bright spots."
