Worst episode so far, characters act out of character
5 January 2018 | by PabloThePirateSee all my reviews

If you've been a fan of this show for a while, you'll find the characters' behavior in this episode hard to believe. First of all, because Sheldon is mad at Leonard, Raj, and Howard for not letting him mine Bitcoin with them, he refuses to tell them where they stored it (he has an eidetic memory). Leonard criticizes him for still being mad about something that happened 7 years ago. Later, however, Leonard finds out that after he gave Penny a laptop as a gift, she gave it to Zack when Leonard and Penny broke up, which causes him to get mad at her. She gave the laptop to Zack 7 years before this episode takes place. Leonard tells Sheldon not to be mad about something that happened 7 years ago, but he gets mad at Penny for something that happened 7 years ago. It has been clearly established that Leonard is a really nice guy, so he would never be a hypocrite like that. Some time after Leonard criticizes Sheldon, Sheldon criticizes Penny for ignoring her customers, and she tells him to shut up and eat his burger. He corrects her, saying that it's a turkey club. She asks, "Didn't you order a burger?" and he answers, "I did, and yet here we are." It's been clearly established that Sheldon complains about even the slightest inconvenience. He would've told Penny that she had gotten his order wrong as soon as she had given him the turkey club. Later, Amy mentions that at Comic-Con, Leonard wiped his nose on Sheldon's Darth Vader cape. Again, it's been clearly established that Leonard is a really nice guy. He would never wipe his nose on someone else's cape. Do the writers really expect us to believe this?
