Happened to me too! Luckily, it has happened in the past, so I have learned to record the one after too, even if I have seen it.
Dunno where you saw up to, but colleagues of his had to operate on the person who swallowed the ice, found the diamond, and then took it to a jeweller - the same one - to get it valued. He realised it was the same, rang the other doctor to find out if it had gone walkies, and the police were called.
Well it was realised THEY didn't actually steal it, then it cut to the doctor and his wife having a drink on the bed, joking about what had happened. Then, I'm sorry to say the sound was a bit muffled, but she said something like "where is it now?", only to realise it was in the ice in her drink and she had swallowed it.
Bit of a let down really, but then apart from one or two of these, I have always seen the end coming.....
