“Legends of Tomorrow” is back and the stage is set for quite a battle in the second half of Season 2. While Rip Hunter (Arthur Darvill) isn’t exactly himself at this point, the Legion of Doom wants information about the Spear of Destiny from him — and they aren’t going to give up until they get it.

The Spear of Destiny is a very important and unique item in DC Comics lore — it was the spear used to pierce the side of Jesus Christ during the crucifixion — and will similarly become a focal point of “Legends.”

“That’s the big MacGuffin for the rest of the season,” executive producer Marc Guggenheim says. “Comic book fans know that there is a connection between the Justice Society and the Spear of Destiny. We’re honoring that.”

With the stakes so high, and the Legion of Doom making things miserable for the Legends, there’s only one way to make things on the show more exciting: The return of Captain Cold (Wentworth Miller).

Thankfully, that moment is coming. After Mick (Dominic Purcell) was essentially haunted by the ghost of his former partner in crime, Guggenheim is excited to reintroduce the character to fans.

“There’s still some pipe-laying we’re doing… [For] the return of Snart,” he previews. “But when you get him, you really get him. He’ll be coming back as a full-on member of the Legion of Doom.”

We simply can’t wait to have Snart back on the show, as a villain or a Legend. Though the inevitable clash between he and Mick is going to be a rough one to watch. Between this and the destruction of Penguin and Nygma on “Gotham,” are no supervillain BFFs safe?

“Legends of Tomorrow” airs Tuesdays at 9 p.m. ET/PT on The CW.
