Last night’s episode of the Colbert Report brought together two people whose beloved shows will soon come to an end: Stephen Colbert, of course, and his guest, Sarah Koenig. Dec. 18 will mark the final episodes of both The Colbert Report and the first season of Koenig’s wildly popular podcast Serial. Colbert interviewed Koenig about what it’s like to be “the world’s first superstar podcaster,” how she came up with the idea for the show and why she changes her opinion over the course of her reporting.

While the interview is mostly lighthearted and mutually complimentary, Colbert touches on one serious question about the way in which the world has changed since 1999, the year the central murder in the podcast was committed. “Do you really think,” he asks, “that a guy named Adnan Syed could get a fairer trial after 9/11?”

Colbert closes by asking perhaps the most pressing question on the minds of the show’s fans: “Can you just tell me if, by the end of the series, that girl ever learns to pronounce MailChimp?” It looks like we’ll have to wait until next week to learn the answer.

Correction appended: The original version of this article misstated the date of the Colbert Report’s finale. It airs Dec. 18.
