I believe I do have a timeline of events that you might find informative.
While playing a round of charades, Deborah calls the rest of the family “spaniels” for deliberately avoiding the correct guess, even though she had already revealed the answer accidentally.
The family each rip up the hat that they get from their cracker, although Alex has to first be reminded to do so.
Instead of Christmas pudding, Deborah has half a scotch egg.
At one point during the call, Alex tells Toby to let their dog, Oswald, out.
Deborah is visiting her father, Jerry. Jerry’s ability to express himself is affected by aphasia. Deborah is supportive in helping him to communicate, but can’t quite suppress a giggle when he says “backwards and forwards” instead of his usual “onwards and upwards”.
The two are attempting to play Scrabble. However, after Jerry plays HVRAST (which he pronounces “hockets”), Deborah is able to convince him that he is not yet recovered enough for the game.
After Jerry is able to sing the first line of We Plough the Fields and Scatter, Deborah realises that the word he was trying to play was HARVEST.
Jerry becomes unexpectedly upset when he realises that they have deflated his lilo. In his shock, he shouts: “What have you done? Oh, you cockers!”
He quickly regains his composure and apologises to them all. He explains that he was keeping the lilo blown up because his wife, Hilla, had been the one who inflated it before she died.
He consoles himself and the others with hugs and his refrain of “half a glass”.
He apologises again for swearing at them. However, they are able to reassure him that his lingering aphasia has actually saved him from doing so. They comfort him by joking that “cockers” was at worst akin to “spaniels”, and agreeing that they had indeed behaved like “complete spaniels”.
Jerry’s ability to express himself is affected by aphasia, but he and the family choose to embrace it. Deborah reminds the audience of how well everyone did on the ‘What would Jerry say next?’ round from his 50th birthday. She jokes that Jerry has now truly turned the tables on that.
Jerry opens by saying “Gently, ladybird, here we come”. Although the speech that follows is very confused and difficult to interpret, it is warmly received by the family.
When he is finished, Jerry raises a toast “To glassware!”, which may be his attempt to say “Half a glass!”.
