The 100 On Tuesday, we said goodbye to someone who was there from the beginning – and if you're a long time fan of CW drama, you know how rare it becomes.

This week's episode, "What You Take With You," marked the latest appearance of Henry Ian Cusick, best known to fans of the series as Marcus Kane. Although her consciousness had already been transferred into a new body, we were treated to a ripping cameo from Cusick while Abby was telling her longtime love a goodbye in tears.

"I have to say that it's a pleasure and an honor to have @hicusick on our show for 6 years," explained Showrunner. Jason Rothenberg tweeted shortly after the episode aired on the east coast. "The guy has graded the seal. We really helped to make it clear that we were not a teen show. Not that something is wrong with teen shows. In any case, we will miss him.

Cusick added"Everything ends and it's Kane. Thanks to @JRothenbergTV and all the editors of the casting team, directors of # the100 but especially to you, #kabby and #kane supporters, your pbadion and support over the years has been truly wonderful and I love them a lot! May we meet again.
