Legends of Tomorrow shocked audiences last spring when it killed off the popular Leonard Snart before the end of the first season. Luckily, Legends of Tomorrow is a time travel show filled with characters who don't really care so much about the rules of time travel, and death isn't always permanent. Now, we know when he'll be back to ice his enemies as Captain Cold once more, as Wentworth Miller will reprise his role as Leonard Snart in the Season 2 midseason finale, and it's probably a pretty major deal for some big reasons.
We already knew that Captain Cold would be back in an important way at some point, since it was announced shortly after the character's death that Wentworth Miller had signed on to The CW's DC universe as a regular who would visit Arrow and The Flash as well as Legends of Tomorrow in the 2016-2017 TV season. A past version of Captain Cold tuned up in the Legends of Tomorrow Season 1 finale, and showrunner Marc Guggenheim teased that the rogue would have a presence in Season 2. Throw in the fact that the Legion of Doom band of villains was stated to include Captain Cold, and it was inevitable that he'd pun his way back to prominence. The question was just of when.
Captain Cold's return in the midseason finale indicates that the Legion of Doom will take its time coming together. The Season 2 premiere revealed that Damien Darhk and Reverse-Flash have already pooled their resources, and Deadline reports that Malcolm Merlyn will join the duo in Episode 8 of Season 2, so Captain Cold will be the last member of the Legion to sign on. Each of the four has been problematic to the good guys of The CW's DC universe on their own; the whole group together with a mishmash of Darhk's magic, Reverse-Flash's superpowers, Merlyn's scheming, and now Cold's technology could be a huge problem for all of time and space.
A midseason finale return for Captain Cold will undoubtedly also raise the stakes going into hiatus. Mick Rory should be glad to reunite with his old partner, and Sara formed a special bond with Cold during Season 1 that she could be keen to rekindle, but they may be in for a rude awakening when they discover that this version Captain Cold is still stuck in villain mode. The Legion of Doom could gain a significant edge over the Legends by bringing him into their crew of evildoers. We'll have to wait and see if they try to go the double agent route and ally him with the Legends, or just send him in with his cold gun at full power.
