Ian's grateful that Lexi and Roy gave the surrogacy plan serious consideration. Roy insists that it all came from Lexi. But he's genuinely sorry they couldn't make it work. Ian's child will be lucky to have such a kind father.
Noluthando's looking forward to returning to South Africa, and isn't even fussed about staying for her birthday. Freddie changes her mind by suggesting she has a party at Lower Loxley. He's finally passed his maths re-sit, so Elizabeth is in a mood to say yes.

He's been interviewed under caution, and there is the threat of prosecution. The pollution is definitely coming from Home Farm.
