Mark Judge — an author and filmmaker who, according to Dr. Blasey, witnessed the alleged assault — was a no-show. So was Christopher Garrett, otherwise known by his high school nickname “Squi.” Mr. Judge and Mr. Garrett were so closely associated with the young Justice Kavanaugh — appearing regularly in entries in his personal calendar in the summer of 1982 — that they became part of a “Saturday Night Live” skit about the Senate confirmation hearings.

At one point during the football game, Justice Kavanaugh prepared to pose for a picture with former classmates. First, though, he instructed everyone to put down their beers, according to a person who witnessed the exchange. (Justice Kavanaugh didn’t appear to be drinking.)

After the Hoyas’ victory, scores of classmates, spouses and friends from the era gathered for a night of drinking and reminiscing at the nearby Pinstripes bistro and bowling venue.

Justice Kavanaugh skipped the evening event — but his presence loomed large. Addressing the crowd, Georgetown Prep’s recently appointed president, the Rev. James R. Van Dyke, noted how the firestorm around the nomination had united the Class of 1983 and the entire school.

“You guys, the Class of 1983, are in some ways my first class,” said Father Van Dyke, according to a recording obtained by The New York Times, noting how “we’ve been all thrown into the mix together.” He added that “I have heard so many of your names.”

Again his voice was drowned out by a chorus of whooping and cheering, as the crowd screamed some of those names: “Squi!” “P.J.!” That would be Patrick J. Smyth, another classmate whom Dr. Blasey said was at the party where she was assaulted. Mr. Smyth was at the Pinstripes event.
