It turned out that we had been gone much later than three minutes. There I was pulling along a completely inert Harry across compartments, no longer talking thankfully, no longer annoying either, but as a drawback for some peace of mind, he was now also hopelessly deaf to any orders I tried barking at him.
Hence me, pulling at his arm like a leash on a dog that stubbornly planted its butt on the sidewalk. I got three-quarters of the way through before I saw our compartment door sliding open with both Ash and Sammy funneling out in that respective order.
For a second, they both shared the same look of worry, then in the next, also in unison, relief quickly took over, spotting heaving and hauling the extra luggage I brought with me… then they noticed Harry's glazed vacant face, and then sprouted that worry once more.
