Buzz surrounding the season 8 finale of CBS' The Big Bang Theory has been circulating around the Internet and the newest information on an upcoming episode, titled Something New, will feature a trek through time.

Carter Matt posted a still photo from the episode and it appears as though it will have a flashback sequence. Given that Lily's (Alyson Hannigan) mane is a different color and its similar look to earlier seasons, her attributes seemingly support that claim of a flashback.

While Barney (Neil Patrick Harris) and Robin's (Cobie Smulders) wedding day should be one filled with utter joy, it will undoubtedly have its share of anxiety. The couple may not even get to the altar for the highly anticipated episode. Since there are 24 episodes signed on for the following season, the possibilities seem to be unlimited.

The planning process for Barney and Robin's wedding will result in sheer procrastination, as last minute arrangements will have to be made. The website added that Robin is desperate to find her "something old" that she buried years earlier in Central Park. 

The site suspected that due to the Marshall (Jason Segel) and Lily plotline for the episode, it appears as though Hannigan's character will be accepting the offer to bid adieu to New York for a year in Rome. However, there's still a considerable amount of time left for the characters to reconsider. Marshall and Lily also ask Ted to help them pack for Italy, and Barney bonds with Robin, Sr."

A new epsiode of CBS' How I Met Your Mother will air on Monday, April 29. Keep checking back for more of the latest details on the show.
