Wentworth Miller's time in the Arrowverse as Leonard Snart appears to be coming to an end, according to a message the actor recently posted on his personal Instagram account.

Cold became a series regular for the first season of Legends of Tomorrow as a member of the crew on the Waverider alongside fellow Rogue Mick Rory. At the end of the season, his character was killed off; however, thanks to an agreement with Warner Bros., Miller has continued to portray the character in both shows thanks to the large part time travel tends to play in the series' plots.

According to his Instagram post, Miller will make his final appearances during Season 4 of The Flash and Season 3 of Legends of Tomorrow before saying goodbye to his role for good.

Airing Tuesdays on The CW, The Flash stars Grant Gustin, Candice Patton, Jesse L. Martin, Tom Cavanagh, Carlos Valdes, Danielle Panabaker and Keiynan Lonsdale. Legends of Tomorrow stars Victor Garber, Brandon Routh, Caity Lotz, Franz Drameh, Maisie Richardson-Sellers, Tala Ashe, Amy Pemberton, Arthur Darville, Wentworth Miller, Nick Zano and Dominic Purcell.
