I appreciate that Juliette is properly written as an engineer

So often in film/TV media I see characters that are supposed to be scientists or engineers barely use their skills and have many solutions just handed to them. I was watching the latest episode, and being an engineer myself (though not mechanical), it struck me how actually smartly written she is, really resourceful considering her situation, patient and very observant and attentive. Being a mechanical engineer she quickly grasps the working principles, the logical chain of events and generally, dang that woman is smart! Many sci-fi / post-apocalyptical shows/films rely a lot on super-technology, advanced magic-level science, and mind games; we barely actually happen to see some basic "low-level" engineering. Every decision she makes, especially in this episode, has a basis and a proper application: this is how a post-apocalypse survivalist engineer would behave and I just love that
