Legends of Tomorrow: The Legion of Doom Kidnaps [SPOILER]

SPOILER WARNING: This article contains spoilers for "Raiders of the Lost Art," the mid-season finale of "Legends of Tomorrow."

When "Legends of Tomorrow" returned for its second season last fall, it did so without its Captain, Rip Hunter. While it looked like Captain Hunter was lost to time and space for the duration of the season, he made a surprising comeback in the winter finale as a Hollywood director in the 1960s.

Tonight's episode -- "Raiders of the Lost Art" -- revealed exactly why Hunter was in 1967 and why he was directing a space odyssey that closely resembled the journey of the Legends. According to Gideon, after scattering the Legends in the Season 2 premiere, Hunter turned off her power so that he could interface with the time drive. The time drive is an extremely dangerous part of the Waverider and exposure to it, while allowing someone to jump through time, could cause brain damage and memory loss.

When the Legends pinpointed the Spear of Destiny's location and came across their missing Captain Hunter, they were baffled that he didn't recognize them. They tried to remind him of who he was, that he was a great Captain, but he couldn't remember anything. Unfortunately, right when the Legends got Hunter back, he was kidnapped by the Legion of Doom (Malcolm Merlyn, Damien Darhk, and the Reverse Flash.) Hunter's abduction infuriated Sara, but Jax was able to remind her that since she was not a woman who gave up easily, the team will soon find Hunter again.

The Legion, who thought they captured the real Rip Hunter, threatened to torture him just as the episode concluded. Once the Legion realizes they can't extract any information from Hunter, they will likely use him as leverage against the Legends, to trade for what they have been pursuing all season long.

The Legends now have exactly what the Legion wants: the Spear of Destiny. According to Nate, the Spear could be used to re-write history -- and not just alter time through aberrations that can eventually be fixed -- but change it permanently. In the coming weeks, the Legends will have to decide what is more valuable to them, their Captain or the power to re-write history.

Tonight's episode also explored the potential reasons why Mick Rory was seeing visions of Leonard Snart. At first, Professor Stein thought Rory was receiving signals via a Time Master implant. After removing the implant, Stein told Rory that the device had not been active in a long time, so Snart couldn't have been communicating that way. While this didn't answer Rory's problem, it did allow for a possible explanation regarding Snart's presumed return to the show.

Stein said that when Snart destroyed the Oculus, he could have been scattered all over the space-time continuum. If Snart exists outside of time, its possible he could be brought back. Considering Wentworth Miller is slated to return to "Legends" and the "Arrowverse," this could be a clue to his whereabouts.
