As Time Goes By Season 1 Episode 4

Surprise, Surprise

Judith persuades Jean to surprise Lionel by going along to his lecture in Nowrich. However, it is Jean who gets the surprise when she finds that Lionel already has a lady friend to stay with. While Lionel attempts to deal with the embarrasing position he is in, as well as his new found reputation as an elephant killer (thanks to Alistair's hyped-up blurb), Jean faces the romantic advances of Alistair.
