Welcome to The Hollywood Reporter's weekly DC TV Watch, a rundown of all things DC Comics on TV. Every Friday, we round up the major twists, epic fights, new mysteries and anything else that goes down on The CW's Arrow, The Flash, Legends of Tomorrow, Supergirl and Fox's Gotham and what it all means. As Legends and Supergirl don't premiere until next week, this edition covers The Flash, Arrow and Gotham.
The Flash season three premiere
WestAllen: The Flash is really leaning into the WestAllen relationship this season after constant delays and near-starts during its first two seasons. Even when Barry (Grant Gustin) reset the timeline and, as a result, hadn't spent his entire life with Iris (Candice Patton), they still found a way back to each other in the new timeline. Iris even told Barry that she felt like something was off her entire life until the day he approached her in CC Jitters, and then all of a sudden everything felt right to her. When he doubted that he could defeat the Rival (Todd Lasance), it was Iris' words of encouragement and his memories of them together that motivated him to win. And after Barry went back and let the Reverse-Flash (Matt Letscher) kill his mother to make things right, the timeline shifted again, but regardless of the new rift between Iris and Joe (Jesse L. Martin), at least Barry and Iris are still going strong. Or has the timeline messed with their relationship as well? That's unclear until we see Iris and Barry meet face-to-face in the new present.
Reverse-Flash: Is he going to return this season? It's already been announced that Reverse-Flash is going to be one of the four major villains this season on Legends of Tomorrow as a part of the Legion of Doom, but his parting words to Barry made it seem like he wasn't done with him just yet.
Alchemy: Viewers got a small taste of this season's big bad in the final moments of the premiere, when Clariss (also Lasance) heard a voice calling his name in the middle of the night, and the word "Alchemy" was scratched onto his mirror. The mysterious season three big bad Doctor Alchemy is trying to awaken the Rival in Clariss in this timeline, but so far, that's all that's been shown of this villain. In the comics, he's a chemist suffering from multiple personality disorder, with one good side and one evil side constantly battling for control. His darker side uses his scientific expertise along with the Philosopher's Stone to transmute elements into different ones, along with discovering ways to defeat the Flash.
Arrow season five premiere
A new Canary: Laurel's (Katie Cassidy) final words to Oliver (Stephen Amell) were revealed via flashback, and it wasn't a plea for him to not go it alone, as the Comic-Con trailer implied. She actually made him promise that she wouldn't be the last Canary. She wants her legacy to live on in someone new. With former Canary imposter Evelyn Sharp (Madison McLaughlin) joining the team this season as Artemis, that leaves the Canary position wide open. Could Felicity (Emily Bett Rickards) be the one to take up that mantle? We certainly thought so last season.
Mister Terrific: Curtis Holt (Echo Kellum) is well on his way to becoming his DC Comics alter ego, Mister Terrific, now that he's decided to be one of Oliver's vigilante trainees. While out searching for one of Felicity's choices for potential new Team Arrow members, Curtis was jumped by some thugs, and he didn't want to feel helpless ever again. He's an Olympic-level athlete but has zero fight training, so his journey to becoming a hero is not going to be quick or easy.
Olicity: Oliver and Felicity may be working well together on Team Arrow, but there's no romantic sparks getting reignited between the two - at least for now. Felicity has a new boyfriend, Detective Malone (Tyler Ritter), and from the way they were acting in her loft, this isn't a new relationship. They're close, possibly even living together. Time will tell if this relationship is for real, or if it's just a delay to the inevitable Olicity reunion.
Big bads: There are three to watch out for this season so far. Tobias Church (Chad L. Coleman) is the gangster uniting all the criminal families and organizations under his leadership, and he has his sights set on taking out Green Arrow. There's the masked archer, Prometheus, which we still don't have any information on aside from him killing a police officer outside the SCPD station. And in the flashback storyline to Oliver's time in Russia being initiated into the Bratva, the Russian mob, the government strongman Kovar (Dolph Lundgren) is somewhere out there, awaiting the moment Oliver tries to kill him to keep his season four finale promise to Taiana (Elysia Rotaru). Without Diggle (David Ramsey) and Thea (Willa Holland) returning to Team Arrow, Oliver's going to need all the help he can get with the amount of bad guys targeting him.
Two Bruce Waynes: After Bruce (David Mazouz) and Alfred (Sean Pertwee) met Bruce's Indian Hill doppelganger, they let him stay in Wayne Manor until they could figure out where he came from and why he exists. Turns out that 514A, or Five as he was nicknamed, couldn't remember anything before waking up in Indian Hill a year ago. All they know about him is that he can't feel pain and has a large scar on the back of his neck. In the middle of the night, Five cut his hair to look like Bruce, stole Alfred's car and met up with Selina (Camren Bicondova), pretending to be Bruce, and Selina fell for it. Is he just trying to get out and experience life now that he's free from Indian Hill, or does he have ulterior motives?
Lee's new love: Gordon's (Ben McKenzie) ex Lee (Morena Baccarin) came back to Gotham permanently after her new fiancé got a job at Gotham General Hospital. What Gordon doesn't know is that her fiancé is the son of Carmine Falcone (John Doman), his season one nemesis. Lee isn't too worried about that connection, but Falcone certainly is. He's extremely wary about how Gordon is going to react when he finds out, and rightfully so. This season, Gordon has been acting on the darkest impulses and his worst qualities, so there's no telling how he's going to handle this news when he finds out.
A new mayor: And in one of the biggest shockers of the hour, Penguin (Robin Lord Taylor) decided that he's done with ruling the criminal underworld of Gotham. He's setting his sights on running Gotham legitimately as mayor, and he bribed/blackmailed the new head of Arkham Asylum into letting his campaign manager Ed Nygma (Cory Michael Smith) go free. The terrible twosome of Penguin and Riddler is officially back together, and Gotham couldn't be more screwed.
