The final credited appearance by Ella Leyers leaving only Jasper and Christina as having appeared in every story.
Xandra Van Welden plays Marianne Termont but previously played Katelijne Everaerts in Se5. She is the first of 3 persons to be recognised as having played 2 different characters in the show.
At 34.45, we see Jasper's glasses for the final time. He doesn't wear them at all in series 3.
