Izzy's a bit out of her element on this one at least. She's much more adept on Earth because she knows how things function there. She knows a lot about the villains and the other heroes. She knows how things fit together. Out here's she kind of lost. But that doesn't mean she'll never get it. She just needs to find the rhythm of things. There will also undoubtedly be other situations that are much more intuitive and straightforward. 

But Izzy really needed to hear this. Going forward, things would've been way worse if she didn't get this talk. Now she can learn and grow. She can get a little closer to being as knowledgeable as she was back home.
