If the success of a show is in part determined by the number of leaked episodes it has to its credit, then "Legends of Tomorrow" is definitely going in the right direction. The freshman show's Season 1 Episode 4 has been leaked on all torrent sites imaginable.

Canada got an early viewing of "White Knight" and almost immediately fans shared a great quality version of the episode online. It has been downloaded by over 13,000 people on Kat and has received positive feedback from almost everyone who watched it.

Episode 4 will be aired on The CW in the US on Thursday,  Feb. 11, 2016, and it will see the rag-tag team of heroes smack in the middle of the Cold War. Rip Hunter (Arthur Darvill) figures out that Vandal Savage (Casper Crump) is planning someone very evil, and that he has tasked a young Soviet scientist by the name of Valentina Vostok (Stephanie Corneliussen) to do his dirty work.

Valentina is expected to be a recurring character in the series, much like Savage. The character has had many aliases in the Comic Book universe, including Negative Woman and White Queen. She is most likely to become a henchman-like character to Savage's super-villain. 

The Legends will be seen breaking into The Pentagon -- the headquarters of the United States Department of Defense -- in an attempt to find out the information they have on Vandal Savage. However, things do not go according to plans, and the Time Masters track him down.

The episode will see the group of heroes and anti-heroes get a bit closer to becoming a team, while a few of them even make personal bonds. It could be pegged as the best episode in the series so far.

Watch "Legends of Tomorrow" Season 1 Episode 4 at 8 pm (EST) on Thursday, Feb. 11, 2016. You can also live stream "White Knights" via CWINGO and The CW Seed.
