As implied in its title, the Season Seven finale of The Big Bang Theory brought with it chaos, as the announcement of Penny and Leonard’s engagement prompted a downwards spiral for Sheldon. Clearly fuelled by the successes of the last episode, the writers continued to be on form, bringing together all of the characters to react to Leonard and Penny’s news whilst tying off loose ends most satisfyingly.
Because The Big Bang Theory is set out in "real-time", we were all waiting for one of the characters to announce a sudden trip, and considering past performances, the likelihood was it being Leonard. However, the big shocker of the episode came with the announcement from Sheldon that he was leaving via train to try to process all the changes in his life and figure out who he is and what he wants from life. It’s rare that Sheldon ever departs from the comfort of his apartment, so this was a big step for the character, sparking speculation as to what he will be like when he comes back from his self-discovery trip. Will we see a changed Sheldon? Or will he still be the same as he has always been? The episode ended on a cliff-hanger in that respect, ensuring viewers would tune in to the first episode of the eighth Season in the fall.
It’s fair to say that the Season Seven finale of The Big Bang Theory was a complete success, as the winds of change blew in to disrupt the happy status quo that certain characters are so used to. This thankfully marked that some things would indeed be changing, and meant a possible shift in character dynamic and progression for the eighth season. The finale ensures that there are plenty of events to look forward to when it returns later this year.
