Unbeknownst to Lexi, Fez came to the New Year's party with only one thing on his mind: to kill Nate Jacobs (Jacob Elordi). Nate turned Fez and Ashtray into the police and Fez was determined to get revenge. In the final scenes of that same episode, before and after Fez beats Nate to a pulp, he shoots Lexi a look. The first one seems to be just a look of acknowledgment and almost an apology for what he is about to do. The second look, after the fight, is one of embarrassment and worry — worry that he may have just scared her off.
