[Seraphim]

I got the impression that they'd agreed not to say they'd been drinking so the others wouldn't feel worse. Jim tried to cheer the others up by saying there was curry and cherry brandy waiting for them. Linda wasn't bothered by Jim telling them, and contradicted him so she could tell the others how it tasted. She only got pissed off when Dappy said "Thanks Jim". It was a task and they always deceive people during tasks then tell them the truth afterwards. They'd have told about the wine afterwards, same as usual, just as the others would have told them that they'd enjoyed great food and alcohol in the bar.
