He at least knew she was planning to go back anyway. For those saying Anakin already does pod racing: Yes, he's skilled at that sport, but that's a vastly different universe compared to a battlefield where you're unarmed against hundreds of droids shooting at you. It's like saying, "Hey, this teen knows how to survive skydiving from thousands of feet in the air! Clearly, we must take him to Syria and risk having him get horribly killed in hundreds of different ways, despite him having zero military training whatsoever!! Ah, I'm sure he'll be fine. He's a skydiver!" Being able to survive a deadly sport is in no way comparable to being on a battlefield. For those saying Star Wars is fictional: You are correct, we know that. That's why we don't see people running around Earth who can throw things with their minds and fight with light sabers, or Wookiee ripping arms out in dingy bars. Within the context of the story, it makes no sense as Anakin has absolutely NO experience in a war, and he's a child. Yes, a child strong in the Force...but still a child. At least with Luke, we saw that he at least had experience shooting things. With Anakin, all he did was follow Qui-Gon around and got a brief "feel, don't think" lesson.
