Jack Coleman’s career hasn’t exactly been an exciting thing to keep track of ever since his last series regular position on Heroes was terminated along with the show itself. He’s wandered around since then, taking small parts on The Mentalist, The Vampire Diaries, and Criminal Minds, with his most significant role – and I use that term only relatively – being the love interest for both Angela and Oscar on The Office. Overall, there has not been much interesting work for Coleman since he hung up his horn-rimmed glasses. But things may be looking up now that he’s secured a tantalizing new part on Castle Season 5.

According to TVLine, Coleman will be slipping into the role of a U.S. Senator, which just so happens to be the profession of his character on The Office. The difference is The Office character was just a guy trying to hide his love for men, while Castle’s senator will serve a more sinister purpose. He’ll function as a new antagonist for Stana Katic’s Beckett. But so far we don’t know why these two will be at odds. A likely bet would be Beckett is investigating something Coleman’s character wants kept a secret. Being a noble officer of the law, Beckett wouldn’t be one to aid in a cover up, a decision that wouldn’t sit well with a senator whose public image is in jeopardy.

And where does Castle come into this feud? I have no idea. More importantly, just how long can we expect to see Coleman on the show? When you hear the word antagonist you tend to think in the long term, but there isn’t really anything to suggest Coleman will be around for longer than maybe a couple episodes. I hope he’ll have a nice long arc on the show, if only so I can see Coleman on my TV screen semi-regularly again. If that’s not the case, then I’ll keep my fingers crossed for something a bit more permanent down the road.
