Casualty’s next episode in its ongoing Learning Curve boxset coincides with Valentine’s Day, but love doesn’t appear to be in the air for Holby City General, and several secrets threaten to rear their heads.

One of the biggest storylines of the past few weeks has been the revelation that Dylan Keogh (Will Beck) is actually Matty Linklater’s (Aron Julius) father, although the latter currently remains blissfully unaware of this.

Last week, fans were surprised when Iain Dean (Michael Stevenson) enjoyed a random fling after estranged wife Faith Cadogan (Kirsty Mitchell) turned down his suggestion to reconcile, but with Faith now believing the couple should reunite, he’s left in a difficult situation.

However, it will actually be Jacob Masters (Charles Venn) and Teddy Gowan (Milo Clarke) taking centre stage next week when Jacob is left blindsided by Teddy’s new girlfriend’s actions.
