Oh I believe it had a huge impact on him. And most of his smiles throughout R2 are forced and him playing a role. That's what got me about 13's smile. He's not playing a role there; he simply slipped for just one second and let himself go back to a simpler time. There will always be three very important people in Suzaku's life, and they alone are the ones capable of making him truly smile: Euphie, Nunnally and Lelouch. The smile in 13 is the same carefree quality as the ones of S1, and that is why Suzaku gets so upset in that scene; he realizes it. Suzaku doesn't want that happiness back, especially around Lelouch. That scene has always fascinated me because it reminded me that no matter what, those three special people for Suzaku will never change.
Maybe I'm an optimist, but Suzaku has a life to live, albeit a very unique one. He is only 18, and he cannot do his reckless life-risking stunts of usual. I think that, in time, Nunnally will make Suzaku smile again. Nunnally, after all, can help Suzaku realize Euphie's dream.
