‘The Big Bang Theory’ season 9 spoilers: ‘Big secret’ coming in Valentine’s Day episode!

Just in case you did not see the commercial that aired during Super Bowl 50, rest assured that there is some big stuff coming on “The Big Bang Theory” Thursday night.

What can we expect? That is what is still a mystery for the time being, since the network did not exactly reveal too much in the way of teasers other than this: Someone has a very big secret, and that will be revealed during the episode! We anticipate a few interesting twists and turns, and more than anything, comedy. We haven’t seen what we would call a defining episode so far in 2016, and this would be a perfect time for that to happen.

If you’re looking to comb through at least some clues in terms of what to expect, check out the official synopsis below:

“Sheldon and Amy host a live Valentine’s Day episode of Fun with Flags, Leonard and Penny grapple with getting older, Howard and Bernadette find a surprise in their hot tub and Raj is torn between Emily and the cute girl he met at the Comic Bookstore.”

By the time we make it to the end of this episode, all will be revealed … though we have a couple of theories right now that are the following:

1. Something big happens for Howard and Bernadette that changes everything for them moving forward.

2. Maybe Raj makes a big decision in his personal life that finally changes things up for him. We’ve been waiting for something big to happen with him.
