Pete Davidson briefly appeared on Saturday Night Live to introduce Miley Cyrus, Mark Ronson, and Sean Ono Lennon. Cyrus, Ronson, and Lennon were there to perform a cover of John Lennon’s “Happy Xmas (War is Over).†Speculation abounded as to whether he would appear at all this week, since he posted a troubling message on Instagram before deleting his account. An NYPD officer did a wellness check earlier and spoke to Davidson at 30 Rock earlier Saturday afternoon. Besides this moment, Pete only appeared in a pretaped sketch about potential new Oscar hosts.
