After Desmond rescues Claire, she tells him that she goes swimming almost every day, but that today she was caught in an undertow, suggesting she was deliberately swimming before being taken out to sea. However, when Claire is rescued, she is fully clothed in normal day wear.
Desmond passes an army recruitment office in London near where
he and Penny pose for the photo. The main army in GB has been known since Cromwell's time as the "Regular Army", not Her Majesty's or Royal Army, hence the distinction of the Regular Army as opposed to the "Royal Navy" and the "Royal Air Force". A recruiting poster displayed spells "Honor", the American way, not "Honour" as it would be spelled in the UK. Also, British Troops do not carry M16s, as shown in the poster.
Moreover, the couple's London flat is shown with stripped stonework and brick. There are no flats in London with interior walls made from rough stone, "London" brick has always been the material. Fine cut blocks of Portland limestone are often used in the exterior walls of office or public buildings but not rough cut stone, except in the North-East of England and Scotland.

After Desmond returned to the island after blowing the hatch, Hurley finds him stark naked in the jungle. However, in the additional scene of his return in this episode, the top of his white underwear is visible.
When Desmond returns from the pub to the apartment there is an electrical plug visible on the wall that is clearly very different from the UK standard plug even though they're supposed to be in England.
