Alistair and Doris Lethbridge-Stewart are looking through their wedding photographs one evening when the Seventh Doctor suddenly appears in some of them. Alistair and Doris both know the Doctor wasn't there — or was he? When the pair begin to vaguely recall having seen the Doctor at the wedding, they wonder if the Time Lord has somehow altered time so he could attend after all.
- Sarah Jane Smith attended the Alistair and Doris' wedding, where she chatted with the Seventh Doctor.
- Doris was originally referenced by Herbert Clegg in the television story Planet of the Spiders, albeit only as someone who had given the Brigadier a watch in a hotel by the sea in Brighton — a matter the Brigadier seemed embarrassed to discuss in detail.
