Brian and the brides
Deb's in charge of hair and makeup, which Mel is protesting, when Brian barges in (I guess people do this enough to him in his loft that he feels entitled to do it too) and sends Deb off so there are fewer witnesses to his act of selflessness. ;)
Of course he deflects Mel's statement that he's responsible for all of this and tosses them their wedding present from him – the rings. :) Engraved and everything.
Linds throws herself on him, Brian warns her not to get moist (lol!), and Mel sort of awkwardly shakes his hand.
