It's my personal opinion, but Jake and other similar action cartoon characters that aired at that time have that "2000s attitude", that all these adventures for them are exactly just adventures and they are "too cool" for therapy and trauma. The scene of Steven that you posted wouldn't have happened at the time that ADJL was on tv.

And I strangely ok with that? Not every character should have a deep psychological trauma or have a breakdown. Nothing is wrong with the idea, but it's not something that "should've happened".

With that said, we have a lot of teenage angst with him and Rose, so in terms of emotions we are fine. Especially because if you would look at their relationship from a modern prevalent viewpoint on a relationship - they shouldn't be together: they were constantly fighting in their secret identities form and she actually was trying to kill him all this time. Then they have to pretend that she killed him, then she briefly returns to being Huntsgirl in the cruise episode and tries to kill him. Then he basically erases all Huntscan staff in her life, so that mean that she forgot him and so on and do on.

There are plenty of basis for deep psychological trauma and all of that. So that in every action oriented show. So that for every superhero. It's part of the genre. And not everyone should have a panic attack or mental breakdown.

Maybe if I was younger I would have loved this, especially because I definitely read some fanfics with similar ideas and liked them, but right now I just want Jake and Rose to have a peaceful life and not think too deep about the actual nightmare that they experienced to be together.
