On the darker side, as adorable as this picture is, I must admit I kind of disagree with what a number of people are saying in the comment section, namely that Cersei may have turned out for the better if she had married Rhaegar. Keep in mind, she was "experimenting" with Jaime around that age, she threatened to have Maggy the Frog's eyes gouged out, she was a vicious bully to Tyrion, etc. Also, this is pure speculation, but...I think Cersei--at least in the books--may have had a hand in her mother's death. In the show, she genuinely misses her mother, but in the books, she regarded her mother's death as an obstacle being removed. Think about that. Joanna knew about her little "experiments" with Jaime and placed them in separate rooms without informing her husband. It doesn't say whether or not she was pregnant with Tyrion at the time, but if she was, it's possible that Cersei may have arranged for something to be put in her mother's food that may have weakened her during the birth and also indirectly led to Tyrion's dwarfism. Again, this is total guesswork, just to be clear, but it makes sense to me. So, this is a cute picture, but Cersei was a budding monster by that point, not an innocent girl with a chance to be a better person.
