On Wednesday's episode, Louis Litt (Rick Hoffman) is seen getting ready for his wedding to Sheila Sazs (Rachael Harris).
In the scene, the lawyer chooses a very formal look for his special day, which prompts his best friend, Harvey Specter (Gabriel Macht) to ask: "Wait a second. Are you wearing a morning coat?” (via Us Weekly).
“Of course I’m wearing a morning coat. Frankly, I’m disappointed you’re not," Louis replied. After some back-and-forth, Harvey then teased: "Louis, you’re not the prince of England," seemingly referencing Prince Harry.
According to the magazine, the finale also shared a montage, honoring Markle -- who played paralegal-turned-lawyer Rachel Zane in the legal drama for seven seasons before departing for life in England.
Markle announced her retirement from acting following her engagement to Prince Harry in November 2017.
“I don’t see it as giving anything up. I just see it as a change,” she said at the time.
