‘The Big Bang Theory’ Season 12 Episode 6 Air Date, Spoilers: Halloween Party Threatens Penny-Leonard Marriage?

“The Big Bang Theory” Season 12 Episode 6 will feature the gang throwing a Halloween party in celebration of the occasion. However, trouble soon ensues as Leonard (Johnny Galecki) starts letting his insecurities get the better of him. Will his marriage to Penny (Kaley Cuoco) be threatened by this simple act of festivity?

In one sneak peek clip of “The Big Bang Theory” Season 12 Episode 6, it’s revealed that the group will be throwing a Halloween party as an excuse to dress up for the holiday. Fans of the series will remember back in the early days of the show when Penny used to throw such parties all the time. This is a rather neat reminder of what the gang was like in the past and how much they have matured since.

Long-time viewers might also remember those days when the characters would dress up in hilarious fashion while laugh-worthy events ensued. Bringing back at least some of those times in “The Big Bang Theory” Season 12 Episode 6 helps in bringing closure to viewers. This is even more important now because of the fact that this is the last season of the show.

However, trouble might be brewing in paradise since another clip of “The Big Bang Theory” Season 12 Episode 6 shows how different the memories of Leonard and Penny are. Specifically, how different the priorities of both characters were in the past. While Leonard remembers the first kiss that he had with Penny back in Season 1 on their couch, his wife only remembers throwing up.

Of course, with the show being what it is, there’s no way that “The Big Bang Theory” Season 12 Episode 6 will see the marriage of these two being ruined by such a petty thing. It would certainly be a surprising turn of events, though, and would really mess with the fans. Viewers will simply have to watch the episode when it airs on Oct. 25 to find out.
