Ascot would admit to the fact that he thinks his ideals are superior, not to everyone else's, just superior. He would also admit to a sliver of intolerance of other's beliefs. He'll try to be more accepting in the future, as well as watch his demeanor, not just around Satoko and Rika, but also around everyone else. The reason why Ascot adopted his 'attitude' at the Struggle lot was because the challenge to his ideals got him riled up, and he was unable to watch himself.
That said, though, even after adopting a more mature attitude towards everyone, he'll still be nervous about meeting Satoko and Rika again, which, in retrospect, is good, as it signals that he's repentant.
One last thing, though, I don't know what Ascot could say to the duo besides the fact that he's sorry for everything. I can't think of other conversation topics.
