It seems that Rick's car accident last season will be a major storyline in the next season of "Castle." 

Season 6 ended when Rick (Nathan Fillion) had a horrible car accident while he was on his way to his wedding with Kate Beckett. A mysterious vehicle was tailing his car, which caused the crash. This cliffhanger episode is where the next season will pick up.

According to spoilers, Rick's bride-to-be, Kate, will try to get to the bottom of everything, and will conduct her own investigation to find out who was behind the accident as she thinks that it was planned.

Previous reports also claimed that Rick's car crash will not be resolved right away. It will take a few episodes to be answered. This is backed up by the recent statement of the show's executive producer David Amann to TV Guide.

Amann said, "After the second episode, the audience will have some but not all of the answers about what exactly is going on ... It's a sufficient amount [of resolution] that the characters can move and get back to life as they knew it, but the effects of what happened to Castle will re-emerge and re-assert themselves later in the season."

It seems that the story about the accident will be given resolution in the two-part episode. However, the storyline will pick up after sometime and will have a follow up later. It is possible that Rick's accident is connected to another major case.

Meanwhile, Rick and Kate will get on with tying the knot next season after the accident. ABC is hushed and careful not to spill any detail about the postponed wedding. However, rumors strongly suggest that the two will get married in season 7.

Andrew Marlowe, the show's creator, told TV Line, "We have something planned that we're kind of excited about, and we hope that people come back and play along. We know that we owe them a wedding that accurately reflects who Castle and Beckett are."

"Castle" season 7 will be back on air on Sept. 29, 9 p.m. on ABC.
