A soy bean

Young Ahsoka was so heartbreaking because, in these scenes, physically she looks like the age she was when she fought in the Clone Wars (13 or 14), but mentally she's like in her 50s and has all the memories and knowledge that her 50-year-old self has. Now, she looks back and realizes that she wasn't trained to fight in a war. The training younglings received was to be peacekeepers. Now, she sees Anakin's lightheartedness and joking nature and, rather than joining in like she once may have done, she's disgusted by it. Now, she sees the pointlessness of the war and how so many people died for nothing. We see a child with the wisdom and understanding of an adult. It pushes the audience to understand more of the tragedy of the Clone Wars and the trauma that Ahsoka carries from it. This was the guilt and anger and sadness she has been carrying for decades.
