Glimpsed on a train

Mrs. Commuter and I were watching Dan Snow's TV programme on the history of the railways last night. Whilst young Dan enjoyed a steam ride on the north Norfolk railway, two familiar faces popped up amongst his fellow travellers. Mrs. Commuter's brother and sister-in-law, no less.  Rather jarring at first, until we recalled that they had holidayed in that area a few months ago. It was only a little cameo scene and we look forward to their next feature.
