Also I've been a listener since the second or third episode.

Several years had gone by since the episode with Kromer.

Which had been featured in every show since the second episode of the first season.

He had been suspended without pay for all but one month since the episode.

Until December 2010, the corner shop was the only business that had stood since the very first episode.

It was the third night since the episode in the tower room.

Since the episode at the library, she didn't want Harry out of her sight.
