Most of the episode "Distant Voices" plays out in Bashir's genetically enhanced mind. Perhaps the only reason Bashir was able to defeat Altovar's attack was because Bashir was enhanced. It's interesting how even though Altovar is inside Bashir's mind, he still doesn't fully understand Bashir's status as a genetically enhanced man in hiding. (This is similar to when Rao Vantika was inside Bashir's head in "The Passenger".) Altovar confronts Bashir about his past failures – the way he quit tennis to become a doctor because his parents would not approve, the way he intentionally missed a question so he would be second rather than first in his class because of the pressure. What was it Bashir's parents didn't approve about tennis? Did they not want Julian to squander the gifts that they presumably paid good hard-earned curency for? Or were they worried that the life of a super-star tennis play would make it more likely that his genetically engineered status would be found out? And, as has been previously discussed, Bashir probably threw that fiber/nerve question not just to avoid the pressure of being valedictorian, but the pressure of possibly be found out as enhanced (and therefore a bit of a cheat).
