Having ended their third season with a literal bang more than two months ago, the ABC series Castle has kept their fans in suspense ever since. Star Nathan Fillion and the rest of the cast of Castle were at Comic Con today to resolve the cliffhanger from the season finale and shed some light on the future of the series. Along with Fillion, who plays mystery novel author, Rick Castle, co-stars John Huertas (Javier Esposito), Tamala Jones (Lanie Parish), Seamus Dever (Kevin Ryan) and Molly Quinn (Alexis Castle) fielded questions from the audience and rewarded the room packed full of Castle fans. Unfortunately, Castle’s muse Stana Katic (Kate Beckett) was unable to attend the event. (This worked out well for one lucky fan, who got to reenact a line of dialogue with Fillion up on stage.) There is a lot to get to about the upcoming season, including new cast members, changing relationships between characters and two special episodes, so hit the jump!
