‘Euphoria’: What Happened to Cassie’s Ex-Boyfriend, McKay?

The Euphoria gang is (mostly) all back together in the latest Season 3 episode, which revolves around Nate (Jacob Elordi) and Cassie’s (Sydney Sweeney) wedding. It’s hard to remember that there was once a time when Nate and Cassie weren’t stuck in their toxic relationship, which began in the Season 2 premiere.

Who could ever forget that tense New Year’s Eve party, when they hook up in a bathroom while Maddy —Nate’s ex and Cassie’s bestie — stands right outside the door? Cassie’s ex, Chris McKay (Algee Smith), is also in attendance at the party. Though unlike Maddy, he’s missing from Nate and Cassie’s wedding. So, whatever happened to McKay? Let’s break down his Euphoria journey and why he’s missing.
