The Big Bang Theory Season 9 Episode 19 Review: The Solder Excursion Diversion

at .  Updated at .

Sheldon has been keeping a secret for years, and now he's finally decided to share that secret with one person on The Big Bang Theory Season 9 Episode 19.

No, he doesn't share it with Leonard, and Leonard knows just about everything there is to know about Sheldon. Instead, he shares that secret with Amy, which shows even further how much his character has changed over the years.

This all comes from the fact that Sheldon has been holding on to his dying laptop. We've all been there. The computer that just gets slower and slower, and then all sorts of weird things start to happen to it. I can totally relate. The computer I'm typing on? Guys, it isn't going to last much longer.

But Sheldon wants to hang on to that computer much longer than he should, and when the thing finally goes kaput, Amy makes the nice gesture of buying him a new one.

His reaction to that is pretty predictable. He's freaked out that someone else made that decision for him. What's not predictable, however, is his reaction to the idea of recycling his old one.

Nope. He's not having any part of that idea, and he doesn't want to say why.

Amy finally convinces him, and it turns out that Sheldon is a very organized hoarder. He has a storage building filled with literally everything he's every owned – down to the broken electronics and plastic bags.

It's all very neat and organized, but still, it's a LOT of stuff.

Amy's reaction is supportive, thankfully. This is something Sheldon views as a weakness, which I think is really interesting for his character. As he tells her, he's always the logical one, but this inability to get rid of his possessions is entirely illogical.

There's also not much humor in this. It's treated as a more serious issue (one that may also speak to Sheldon being Autistic – I'm not sure) giving him an important way to bong with Amy.

Howard and Leonard's story is secondary to this. It's funny enough, balancing out the more serious nature of Sheldon's story.

Plus, Penny gets the chance to work in the lab, even commenting on how much she's changed since she met these guys. She's even learned a little something about science.

Oh, they went to the store to get solder. Which is metal you melt to make science things.


Howard and Leonard lie about screening a film while Penny and Bernadette work on their prototype, which rings a little false and is resolved pretty quickly. The good news is they decide to tell the truth before they actually get busted, and Penny and Bernadette really don't care much anyway.

Apparently, working on the prototype is pretty fun.
