Michael Trucco is a sought-after, busy actor.
The former Battlestar Galactica star guest-starred on V this week in the key role of John May.
On Monday night, meanwhile, he'll kick off a multiple-episode arc on Castle. Trucco will come aboard the series as Detective Tom Demming, a love interest for Beckett.
This might cause some friction and awkwardness between Kate and Castle, but look at the photos of Trucco below, courtesy of the episode "Den of Thieves." Can you really blame Beckett?!?
